Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many electrons should Carbon have around its Lewis dot model?
A
1
B
3
C
4
D
5
Explanation: 

Detailed explanation-1: -For carbon, there are four valence electrons, two in the 2s subshell and two in the 2p subshell. As usual, we will draw two dots together on one side, to represent the 2s electrons.

Detailed explanation-2: -An atom is indicated by its symbol with a number of dots representing the number of valency electrons e.g Hydrogen would be H with a single dot, Carbon would be a C with four dots.

Detailed explanation-3: -Electron-dot structures of some elements are shown below. In period-4, Germanium has four electrons in its electron-dot structure.
