Explanation:
Given parameters:
Number of protons = 6
Number of electrons = 6
Number of neutrons = 8

Mass number = ?
Solution:
The mass number of an atom is the sum of protons and neutrons in an atom;
Mass number = number of protons + number of neutrons
Mass number = 6 + 8 = 14
Because group 1a and 2a are most reactive due to their least number of electrons in their outmost shell compared to group 8a(18)
