An atom has a small
positively
charged nucleus surrounded by orbiting
negatively charged electrons.
Atoms have a radius of about 1 x 10-10 metres.
Protons have a charge of
+1
and a relative atomic mass of
1.
The proton number is the amount of
protons
the atom has.
Electrons have a charge of
-1
and a relative
atomic mass
of
1/2000.
The number of electrons is the same as the number of
protons.
Neutrons have no charge or
0
, and have a relative atomic mass of
1.
Sub shells are made up of
orbitals.
