What will be the composition of the nucleus of the atom of an element with atomic number 19 and mass number 39?

Text Solution

Verified by Experts

Atomic number of the element (Z) = 19
Mass number of the element (A) = 39
Number of protons in the nucleus = Z = 19
Number of neutrons in the nucleus = A-Z = 39 - 19 = 20
