50 free Ernest Rutherford trivia questions with answers — science & nature quiz, new questions added Aug 2026.
This Ernest Rutherford trivia quiz covers the New Zealander they call the father of nuclear physics. The easy questions handle the gold foil experiment, the nucleus, alpha, beta and gamma, the proton, half-life and the Nobel Prize that, to his amusement, was for chemistry. From there it moves through the life: the misspelt birth certificate, the flax mill, the rugby, the scholarship to Cambridge as an 'alien', the radio record Marconi took away from him, and the Montreal years with Frederick Soddy. The harder end covers thoron, the tissue-paper quote, the piezoelectric submarine work, the atomic numbering system with Moseley, the nitrogen-into-oxygen reaction, the 1933 'moonshine' speech that set Szilard thinking, the neglected hernia, the peerage title, the element with his name and the banknote he still appears on. Every answer was checked against Rutherford's encyclopaedia entry before publishing and the supporting sentence is stored with each question. Our physics and famous physicists quizzes are the natural next stop.

Q 01Rutherford, a physicist, won his 1908 Nobel Prize in which other subject?
Chemistry
Chemistry. The prize honoured his work on how radioactive elements change, and he joked that the quickest transformation he had ever seen was his own, from physicist to chemist.
Q 02Rutherford is widely known as the father of which field?
Nuclear physics
Nuclear physics. He showed that an atom's mass is packed into a tiny central nucleus, then ran the Cambridge laboratory where his students first split one with a machine.
Q 03How was Rutherford's first name mistakenly written on his birth certificate?
Earnest
Earnest. He was officially registered with the stray 'a', but the misspelling never stuck, and to his family he was simply Ern.
Q 04Before raising twelve children, Rutherford's mother, Martha, had worked as what?
Schoolteacher
Schoolteacher. Martha Thompson had taught at the Spring Grove school, and all her own children learned their reading and writing from her.
Q 05Rutherford won the scholarship that took him to Cambridge only after the first-choice candidate did what?
Turned it down
Turned it down. The examiners ranked James Maclaurin of Auckland first, but he could not accept the scholarship's terms, so it passed to Rutherford, the only other candidate.
Q 06Which sport did Rutherford play at college in the 1880s?
Rugby
Rugby. He played in the school team in 1889, the year he was head boy, though his real strength was mathematics, which later won him a university scholarship.
Q 07Rutherford's 1851 Research Fellowship took him in 1895 to which Cambridge laboratory?
The Cavendish
The Cavendish. He came back in 1919 as its director and never left, presiding over 1932, when his team found a new particle and split the atom by machine within months.
Q 08In 1895 a new rule let Rutherford become Cambridge's first research student without what?
A degree from the university
A degree from the university. Cambridge had just opened its laboratories to graduates of other institutions, and Rutherford, arriving with three New Zealand degrees, was first through the door.
Q 09Under which Cambridge physicist did Rutherford study from 1895?
J. J. Thomson
J. J. Thomson. He soon moved Rutherford from radio waves to X-rays and gases, and later told McGill he had never had a student with more enthusiasm or ability for original research.
Q 10Rutherford's half-mile record for detecting radio waves was soon eclipsed by which wireless pioneer?
Guglielmo Marconi
Guglielmo Marconi. Rutherford's professor pulled him off wireless to study X-rays instead, leaving Marconi to turn the idea into a business.
Q 11Rutherford's early Cambridge work on X-rays and gases fed into the 1897 discovery of what?
The electron
The electron. His professor went on to weigh the charged particles in those gases and found one far lighter than any atom, while Rutherford turned to the new rays from uranium.
Q 12In 1898 Rutherford took the Macdonald Chair of Physics at McGill University in which city?
Montreal
Montreal. The research he did there over nine years earned his Nobel Prize, though the award came in 1908, the year after he had left Canada for England.
Q 13Which young chemist, a future Nobel laureate, joined Rutherford at McGill from 1900 to 1903?
Frederick Soddy
Q 21Rutherford and Thomas Royds proved that alpha particles are what?
Helium nuclei
Helium nuclei. They let alpha particles collect in a sealed, evacuated glass tube, sparked it, and watched the unmistakable spectrum of helium slowly appear.
Q 22Which student, working with Rutherford's assistant, first saw alpha particles bounce back off gold foil in 1909?
Ernest Marsden
Ernest Marsden. He was an undergraduate handed the search as a training exercise that nobody expected to succeed; he went on to lead scientific research in New Zealand.
Q 23Rutherford likened the gold foil result to a 15-inch shell bouncing back off what?
A piece of tissue paper
Frederick Soddy. Rutherford, a physicist, needed a partner with a chemist's bench skills to separate the new radioactive substances; Soddy later gave science the word 'isotope'.
Q 14Which German chemist, later a discoverer of fission, worked under Rutherford at McGill in 1905-06?
Otto Hahn
Otto Hahn. He arrived having just found one new radioactive substance and found more in Rutherford's laboratory; his Berlin experiment split uranium in 1938, a year after Rutherford died.
Q 15Which term that Rutherford introduced for radioactivity is now also used of drugs in the body?
Half-life
Half-life. He found that the radioactive substance given off by thorium lost half its strength in about a minute, however much of it he began with.
Q 16Rutherford's 'Law of Radioactive Change' made what then-radical claim about radioactivity?
Atoms disintegrate spontaneously
Atoms disintegrate spontaneously. Until then the atom had been thought indestructible; now thorium and radium were caught slowly turning themselves into other elements.
Q 17What name did Rutherford give in 1903 to the penetrating radium radiation Paul Villard first noticed?
Gamma rays
Gamma rays. Villard had spotted them in 1900 without giving them a name; Rutherford, who had already labelled alpha and beta rays, simply took the next Greek letter.
Q 18At a 1904 lecture, Rutherford's case for a far older Earth contradicted which elderly physicist in the audience?
Lord Kelvin
Lord Kelvin. Rutherford recalled that Kelvin dozed until the awkward part, so he quickly said Kelvin's estimate had assumed no new kind of heat would be found, and radium was one; the old man beamed.
Q 19In 1907 Rutherford returned to Britain to take the Langworthy Professorship at which university?
Manchester
Manchester. The post was free because Arthur Schuster, who had built up the physics laboratory there, gave up his own chair early on condition that Rutherford take it.
Q 20The particle detector Rutherford built with an assistant in 1908 evolved into which instrument?
Geiger counter
Geiger counter. The 1908 original was built to count alpha particles one at a time in the laboratory; Hans Geiger made it a practical instrument with Walther Muller in 1928.
A piece of tissue paper. The image comes from a lecture late in his life; the rebound had convinced him that an atom's mass sits in a tiny charged core, later named the nucleus.
Q 24Rutherford's gold foil results showed that an atom is mostly what?
Empty space
Empty space. Almost every alpha particle flew straight through the foil as if nothing were there; only a rare one met something small and dense enough to turn it back.
Q 25During the First World War Rutherford worked for the Admiralty on detecting which threat?
Submarines
Submarines. With William Bragg he concluded that the best hope was to listen for them underwater, and the hydrophone he developed became the only patent of his life.
Q 26Which young physicist in Rutherford's laboratory used X-rays in 1913 to give every element an atomic number?
Henry Moseley
Henry Moseley. His measurements put the elements in order by nuclear charge and showed where undiscovered ones were missing; he was killed at Gallipoli two years later, aged 27.
Q 27Rutherford's bombardment of nitrogen with alpha particles, reported in 1919, achieved the first artificial what?
Nuclear reaction
Nuclear reaction. He showed that alpha particles could knock hydrogen nuclei out of nitrogen, the first time anyone had deliberately broken into an atomic nucleus; it is remembered as splitting the atom.
Q 28What did Rutherford name the hydrogen nucleus in 1920, proposing it as a building block of nuclei?
Proton
Proton. He drew it from the Greek for 'first', reportedly echoing William Prout's old idea that hydrogen builds every element; until then he had simply called it a hydrogen atom.
Q 29Patrick Blackett showed that Rutherford's bombardment of nitrogen with alpha particles produced which element, alongside the ejected particle?
Oxygen
Oxygen. Rutherford had seen only the particle that flew out; Blackett's cloud-chamber photographs caught the rare forked tracks where nitrogen swallowed the alpha and became a heavier element.
Q 30Which particle did Rutherford predict in 1920, twelve years before it was discovered in his own laboratory?
The neutron
The neutron. Nuclei weighed about twice what their charge allowed, so he argued something neutral was hiding inside; James Chadwick, primed for years on what to look for, found it in 1932.
