d)
(e)​

Answer 1

I don't know but plz help me

Answer 2

Let us solve for it

Explanation:

The list of elements are :

A (Z =6) B (Z=8) C(Z = 10) D (Z = 12) E (Z = 14), F (Z=16)

The electronic configuration for them are :

A =2,4

B=2,6

C=2,8

D=2,8,2

E=2,8,4

F=2,8,6

The elements which has :

1. Two shells both of which are completely filled with electrons ---> C
2. The electronic configuration 2,8,2 --> D
3. The total of three shells with four electrons in valence shell --> E
4. A total of two shells with four electrons in valence shell --> A
5. An element that is basic for all organic compounds --> A
