If two shells overlap, they start to share electrons and thus, a bond is formed
Answer:
Explanation:
Fe⁺²(aq) + ClO₂(aq) → Fe⁺³(aq) + ClO₂⁻(aq)
Here oxidation number of Fe is increased from +2 to +3 , so Fe is oxidised .
The oxidation number of Cl is reduced from + 4 to +3 so Cl is reduced .
So ClO₂(aq) is oxidising agent and Fe⁺²(aq) is reducing agent .
M IS A LETTER but N is a letter
It has a negative charge emits energy when it moves to a lower energy orbit from an excited state and it has the same mass as a proton
