Question

Electronic configuration of four elements are given in the table. Arrange these elements in the increasing order of the electronegativity. Give reasons
Elements = Electronic configuration
Na = 2,8,1
S = 2,8,6
Al = 2,8,3
K = 2,8,8,1

​

Answer 1

Answer:

Explanation:

increasing order of the electronegativity.

1)Na = 2,8,1

2)Al = 2,8,3

3)K = 2,8,8,1

4)S = 2,8,6

As we move left to right of the periodic table period wise the electron negativity increases

but as we go down a periodic table group wise the electron negativity decreases.

Answer 2

Answer:

Explanation:

Increasing order :K, Na, Al , S
