Question

what is the periodic property?How do the following properties vary in a group and in a period ? i)Nature of oxides ​

Answer 1

Explanation: Reason: As we go from left to right in a period, the atomic radius gradually decreases. As a result of which, the attraction between the added electron and the nucleus increases. Hence, electron affinity increases in a period. In a group as we go from top to bottom the electron affinity values gradually decrease.

Answer 2

Explanation:

Electronegativity values of elements decreases as we go down in a group. Period : Electronegativity increases along a period from left to right. Ionization energy increases from left to right in a period. Ionization energy decreases from top to bottom in a group.
