Atoms Atoms are the building block of all matter and are

the simplest form of molecule. They are all made up of protons, neutrons and electrons. They look something like this:

The nucleus:This contains neutrons and protons.

Electrons:These orbit around the nucleus

Timeline

The ideas of the structure of the atom changed over time.

Democritus 460-370 BC

450BC

One of the first scientists to study the Atom, he thought that all atoms are made of small indestructible particles, and that there are an many atoms and are all in different shapes and sizes.

John Dalton1766-1844

AD1803 AD

He found out that different elements have different atoms and that all atoms of the same element are identical.

Eugene Goldstein1850-1930

1886 AD

He discovered the existence of the proton and the positively charged particles.

Joseph John Thomson

1856-1940

1897 AD

Joseph Thomson discovered the electron. He also invented the Plum-Pudding model, in his model electrons and protons are mixed together.

Albert Einstein

1879-1955)1905 AD

Einstein found out the light was an amount of energy called photons.

Robert Millikan

1868-19531909 AD

Robert found out the actual charge and weight of an Electron.

Ernest Rutherford 1871-1937

1911 AD

In his Gold-Foil experiment he discovered that the atom was mostly empty but had a solid center that is the nucleus.

Niels Bohr1885-1962

1913 AD

Bohr discovered that electrons are found in circular paths called orbits which move around the nucleus.

Louis de Broglie

1892–19871923 AD

He found out an equation which shows that particles of matter sometimes behave as waves.

Erwin Schrödinger1887-1961

1926 AD

He invented an equation which could describe energy waves.

Page 14: Atoms Atoms are the building block of all matter and are the simplest form of molecule. They are all made up of protons, neutrons and electrons. They

James Chadwick1891-1974

1932 AD

He discovered the other part of a nucleus of an atom that has no electrical charge called the neutron.

The ideas of the structure of the atom have changed over time since the technology and sources have improved and also by taking another idea of someone else and improving and building on it.
