HUU UUUUU.ULILULLL UIL CUITUL alls wel llUITT Te given

An element has electronic configuration 1s22s 2p 3s 3p4. Predict their
period, block and group.
1
Period = 34, block =p, group = 16
2 Period = 5th , block = s, group = 1
3
Period = 3rd, block =p, group = 10
4
Period = 4th , block = d, group = 12​

Answer 1

Answer:

block = p, group = 16

Period =

, block = s, group = 1

Period =

, block = p, group = 10

Period =

, block = d, group = 12

Answer :

A

Solution :

By observing principal quantum number (n), Orbital (s, p, d, f) and equating no. of

's we are able to find the period, block and group of element in periodic table.

Answer 2

Answer:

1=> 3rd period , p block , group 16

Explanation:

electronic configuration = 1s2 , 2s2 , 2p6 ,3s2,3p4

Number of shells = 3

hence the period will be 3

atomic number =16

group = number of valence electrons + 10

= 6 + 10

= 16

hope it helps you
