2.3 How many neutrons and protons are there in the following nuclei?
Given the nucleus of Magesium:
Atomic number (Z) = 12
Mass number (A) = 24
Number of protons (Z) = 12
Number of neutrons (A-Z) = 24-12 = 12
Given the nucleus of carbon:
Atomic number (Z) = 12
Mass number (A) = 24
Number of protons (Z) = 12
Number of neutrons (A-Z) = 24-12 = 12
