Protons and neutrons together are called Nucleons.
An element can be represented as X4 where X is an element, A is the mass number and Z is the
atomic number.
A= Number of protons + Number of neutrons = A=Z + n => n= A-Z
In the above information
In the expression, the letter 'Z' represents
I 1
a) Atomic number b) Mass number c) Symbol
d) Oxidation number​

Answer 1
