Solution

The correct option is D 14
For a neutral atom,
number of protons = number of electrons
We know that,
Mass number = Number of protons + Number of neutrons
For the given atom,
Mass number = 27
Number of protons = Number of electrons = 13
Number of neutrons = Mass number - Number of protons
Thus, number of neutrons = 27 - 13 = 14
