Question

please tell this answer

Answer 1

Answer:

Zz

Explanation:

Answer 2

1) most reactive non metal is Flourine

It will get electron so easily

So its first EGE will be least (-328)

So 1 - - > b

2) most reactive metal is Cesium

It will loose electron so easily

So we have to give minimal energy to get the electron

(IE1 will be least) (419)

Second IE will be high because Cs+ is very stable it won't allow to get more electrons

Now

2) - - - > a

3) Least Reactive Elements are Noble Gases

In That Helium, its IE will be sooooo high

So 3----> d

And 4- - - - > c
