Answer:
ALL ISOTOPES OF AN ELEMENT HAVE THE SAME NUMBER OF;
1. PROTON
2. ATOMIC NUMBER
Explanation:
Isotopes are atoms with the same atomic number but different mass numbers. Isotopes of an element has the same number of proton which dictates the atomic number of the atoms. The difference in mass number is as a result of the difference in the number of neutrons. Isotopes of an atom have different physical properties but they exhibits the same chemical properties because neutrons have no influence on the chemical properties and the change or difference in neutrons will produce no effect on the chemical properties of the atoms. Neutrons only contributes to the mass of the atoms giving the isotopes of an atom different mass numbers. An example is chlorine with two isotopes, Cl -35 and Cl -37.
Properties Cl-35 Cl-37
mass number 35 37
atomic number 17 17
number of protons 17 17
number of electrons 17 17
number of neutrons 35-17 = 18 37-17 = 20
abundance in nature 75% 25%

Explanation:
When atoms forms ion, they either lose or gain electrons.
In an atom, we have three subatomic particles;
- Protons are the positively charged particles
- Electrons are the negatively charged particles
- Neutrons carry no charges.
A neutral atom has equal number of protons and electrons.
A positively charged atom has more protons than electrons which implies that they have lost electrons.
A negatively charge atom has more electrons than protons suggesting that they have gained more electrons.
If we are given Na, it will for Na⁺ when it loses the electron in its outermost shell. Hence the number of protons is now more and the atoms is positively charged.
