Question

Relation between atomic number (Z), neutron number (N) and mass number (A) is ______.

विकल्प

• Z = A + N

• Z = A + 2N

• A = Z - N

• A = Z + N

Answer 1

Relation between atomic number (Z), neutron number (N) and mass number (A) is A = Z + N.

Explanation:

Mass number (A) = total number of nucleons
= number of protons + number of neutrons
= atomic number (Z) + neutron number (N)
