Answer 1

1st part:-D

2nd part:-L

3rd part:-B

4th part:-F

Explanation:

For the first part,

when we move from left to right then,electron affinity and ionisation energy and from bottom to top then, electron affinity and ionisation energy increases therefore,in group 1 the element with highest ionisation energy is A and lowest is D.

For 2nd part,

when we move from right to left or top to bottom then, atomic radius of elements increases and thus,their metallic properties increase hence,L element is left to M and then,L element has more metalic character and lowest electron negatively.

For 3rd part,

it is same as 2nd part,and the answer is B since it is more left in table than I

For 4th part,

Since elements in same Group resembles most of the properties in them,therefore F is in the same grop that E has and thus, F will resembles most of the properties that E have.
