Question

Q4. Given table consists of elements with their atomic number, identify the electronic configuration of which noble gas
does the element try to achieve.
Element Atomic number Nearest noble gase
Phosphorous
15
Chlorine
17
Sodium
11
Boron
5
Calcium
20

Answer 1

Answer:

Ok, first you will need the periodic table. Even if you don't have no problem.

Phosphorus will try to achieve electron configuration of Argon (Ar) electron configuration- 2,8,8

Chlorine  will also try to achieve electron configuration of Argon (Ar) electron configuration- 2,8,8

Sodium will also try to achieve electron configuration of Argon (Ar) electron configuration- 2,8,8

Boron will try to achieve electron configuration of Neon (Ne) electron configuration- 2,8

Calcium  will try to achieve electron configuration of Krypton (Kr) electron configuration - 2,8,18,8
