Question
An atom has 7 electrons in its M-shell and contains 18
neutrons in its nucleus. What is its mass number?Solution
The atom has 2 electrons in K, 8 electrons in L and 7 electrons in M = 2 + 8 + 7 = 17 and nucleus has 18 neutrons, so its mass number = (number of electrons + neutrons) = 17 + 18 = 35.
