The mass number of element is 22.

The mass number is the sum of number of electrons/proton and number of neutron .

Mass number = number of proton/electron + number of neutrons

If an element with 11 neutrons, 11 protons, and 11 electrons then mass number is calculated as,

Mass number = number of proton/electron + number of neutrons

Mass number = 11 + 11 = 22
