Answer:
Explanation:
There are three fundamentally known subatomic particle which resides in an atom. They are :
Protons Neutrons Electrons
Protons are positively charged particles located in the nucleus of the atom
Neutrons do not carry any charges and reside in the nucleus with protons
Electrons are negatively charged and they orbit the atom
Protons and neutrons determines the mass of an atom. The mass of electrons are negligible.
Mass number = Protons + neutrons
A neutral atoms is one in which the number of protons and electrons are the same.
