Atomic Notation
Atomic number (Z) is the number of
protons in the nucleus of an atom. The
number of protons equals the number of
electrons in a neutral atom
Mass number (A) is the sum of the
number of protons and the number of
neutrons in the nucleus of an atom.
So how can you work out the number of neutrons in
an atom?
No. of neutrons = Mass number – atomic number
