Atoms – what do you know?
Here is a picture of a carbon atom.
Complete the sentences below:
All atoms are made up of three particles. There are _______________ which are
positive, _______________ which are negative, and _______________ which
have no charge.
The centre of the atom is called the _______________.
Atoms are not charged so the numbers of _______________ and
_______________ is the same. If you remove an electron the atom becomes an
