Element mass number atomic number aluminum 27 13 nitrogen 14 7 helium 4 2 fluorine 19 9 which element has the most neutrons in the nucleus? aluminum nitrogen helium fluorine

Aluminum

Explanation:

An atom of any elements has an outer electron and a proton and neutron located in the nucleus . The proton and neutron found in the nucleus of an atom determine the mass number of an element. The mass number of an element is the sum of the proton(atomic number) and the neutron number.

Mathematically,

Mass number = proton number(atomic number) + neutron number

Therefore,

neutrons number = mass number - proton number

Aluminium has the highest neutron  

neutron = 27 - 13 = 14

Neutron of aluminium = 14
