The Atom

Page 1

The proper name for particles are ATOMS.

Everything around us is made up of tiny atoms. Atoms are made up of 3 smaller particles called;

- Protons

- Neutrons

- Electrons

The Protons and Neutrons are always together in the centre of the atom called THE NUCLEUS.

The tiny electrons always spin around the nucleus.

The Protons, Neutrons and Electrons are very different from each other .

Particle Charge Location Mass

Proton (+) Positive In The Nucleus 1 a.m.u

P

Neutron (o) neutral In The Nucleus 1 a.m.u

N

Electron (-) negative In The Nucleus 0

E

The Mass Number tells us the number of protons and neutrons in an atom.

The Atomic Number tells the number of Protons in an atom.
