Answer the following questions on the basis of the given table:
|
Name of element |
Electronic configuration |
|
X |
1s2, 2s2,2p6,3s1 |
|
Y |
1s2, 2s2,2p6,3s2,3p5 |
|
Z |
1s2, 2s2,2p6,3s2,3p6 |
- Write the name of elements indicated by X and Y.
- Write the blocks of the element X and Z.
- Write the valency and chemical nature of element Z.
1 Answer
1.
X= Sodium, Y= Chlorine
2.
X= S-block, Z= P-block
3.
Valency of Z is "O". Z is inert gas so, It does not take part in chemical reaction.
