How many neutrons does silicon have if its mass is 28?
14 neutrons The atomic number is equal to the number of protons in the atom, therefore silicon has 14 protons. In a neutral species, the number of protons equals the number of electrons so silicon also has 14 electrons. The mass number is the number of protons plus neutrons, therefore 28 – 14 protons equal 14 neutrons.

How do you find neutrons and electrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
What is a neutrons mass?
neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
