Solution

The correct option is B 11, 11, 12
Number of protons = number of electrons

Atomic Number = 11

Atomic mass = number of neutrons + number of protons

So, Number of neutrons = 23 - 11 = 12

The correct option is B 11, 11, 12Number of protons = number of electrons Atomic Number = 11 Atomic mass = number of neutrons + number of protons So, Number of neutrons = 23 - 11 = 12

The correct option is B 11, 11, 12
Number of protons = number of electrons

Atomic Number = 11

Atomic mass = number of neutrons + number of protons

So, Number of neutrons = 23 - 11 = 12
