If you mixed chlorine, argon, and sodium together, just by mixing there will be no changes or reaction that would happen since the energy in mixing the substances is not enough to let a reaction happen. However, if enough energy is added to the system sodium and chlorine might react and form sodium chloride.
Answer:
They lose two electrons.
Explanation:
When an atom loses are gain the electrons ions are formed.
There are two types of ions.
Anion
Cation
1 = Anion
It is formed when an atom gain the electrons. when atom gain electron negative charge is created on atom. For example.
X + e⁻ → X⁻
2= Cation
It is formed when an atom loses the electrons. when atom lose electron positive charge is created on atom. For example.
X → X⁺ + e⁻
There are two valance electrons in group two elements. They loses two electron to complete the octet and form cation with a charge of +2.
For example:
Mg → Mg⁺² + 2e⁻
