C2 1.1 AQA Science © Nelson Thornes Ltd Atomic Scientists C2 1.7 How have our ideas about atoms changed over the years?
C2 1.1 AQA Science © Nelson Thornes Ltd My name is Democritus and I am the father of the atomic theory! I was born in 460 BC, and put forward the idea of atoms. Even the word ‘atom’ comes from a Greek word meaning ‘cannot be cut’. I suggested that atoms were the smallest possible particles and that everything in the world was made from them stuck together in different patterns.
C2 1.1 AQA Science © Nelson Thornes Ltd My name is John Dalton and I was the first modern man to take atoms seriously. I was born in I suggested that atoms are small, cannot be broken apart and join together to make everything around us. We know that water contains hydrogen and oxygen so I suggested that one atom of hydrogen linked with one of oxygen to make a new compound – water! Democritus? Never heard of him!
C2 1.1 AQA Science © Nelson Thornes Ltd My name is J. J. Thompson but my friends call me JJ. I was born in 1856 and spent a lot of time working in the famous Cavendish Laboratory in Cambridge. I put forward the ‘plum pudding’ model of the atom based on work I did with cathode ray tubes (the thing you used to use for televisions). I suggested an atom consists of a tiny sphere with even smaller, negatively charged particles called electrons embedded in it … like fruit in a Christmas pudding! Pity Dalton didn’t know about electrons.
C2 1.1 AQA Science © Nelson Thornes Ltd My name is Ernest Rutherford. I was born in 1871 in New Zealand. I actually worked with ‘JJ’ and built on his plum pudding model to show that most of the atom was empty. Most of the mass was held in a tiny central nucleus with electrons flying around it like planets around the Sun. When JJ retired I took over his job at the Cavendish.
C2 1.1 AQA Science © Nelson Thornes Ltd My name is Neils Bohr and I was born in 1885 in Copenhagen. I worked with Rutherford and JJ Thompson and in 1913 I published a paper that showed how electrons flying around the atom fitted into shells – they didn’t just move randomly! I worked hard all of my life on atomic physics and only just escaped from Germany when the Nazis came to power. I ended up for a while in America where I worked on the atomic bomb project. After the war I spent a lot of time campaigning for peaceful uses of nuclear technology – including writing to the United Nations.
C2 1.1 AQA Science © Nelson Thornes Ltd My name is James Chadwick and I was born in 1885 in Cheshire. And yes, I also worked with Rutherford! My discovery was the neutron. It’s a tiny particle in the nucleus with a mass of one unit but no charge at all. It explains how different atoms of the same element can have different weights. It was an essential part of the theory that has led to the modern understanding of atoms.
