Answer:
Proton = 119
Electron = 119
Neutron = 183
Explanation:
Mass number (A) = 302
Atomic number (Z) = 119
Proton = atomic number = 119
Since there is no charge on the element, it means the element is neutral.
Therefore,
Electron = proton = 119
Mass number = proton + Neutron
Neutron = Mass number — proton
Neutron = 302 — 119
Neutron = 183
