The optimal number of neutrons for a nucleus containing 70 protons is 130
Further explanationIn chemistry, the nucleus is the positively charged center of the atom that consist of protons and neutrons. It's also known as the "atomic nucleus"
The neutron is a subatomic particle with no net electric charge and a mass slightly greater than that of a proton. The neutron is have symbol n or n⁰. Protons and neutrons constitute the nuclei of atoms.
Neutron is a type of atomic particle which does not possess any kind of charge on it. It has neutral behavior toward atoms since it does not possess any kind of charges but it contributes to the mass of the atoms.
Atomic number = 70
Atomic weight = 173
Atomic weight = number of protons + number of neutrons
Atomic number = number of protons
Therefore, the number of protons = 70
Number of neutrons = atomic weight - number of protons
Number of neutrons = 173 - 70 = 103
Optimal number of neutrons = 130
