Question

write the electronic configuration of the elements and compound 1) Na 17 2) Mg12 3) Cl 17​

Answer 1

Answer:

13Al, 14Si, 11Na, 12Mg, 16S

Electronic configuration of the following elements is:

13Al=2,8,3

14Si=2,8,4

11Na=2,8,1

12Mg=2,8,2

16S=2,8,6

11Na has the highest metallic character because the metallic character of an element decrease as we move from left to right in a modern periodic table. this happens as the tendency of an atom to lose electrons decreases due to a gradual increase in the number of protons and nuclear charges.

Answer 2

Explanation:

Na- 2,8

Mg- 2,8,2

Cl- 2,8,7
