Solution

The correct option is D 14
For a neutral atom, number of protons = number of electrons
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
Number of neutrons = 27-13
Number of neutrons =14
