What is the Lewis dot structure for H H?

Answer 1

The Lewis Dot Structure for Helium (He) is,



* He :


When Helium wants to bond with another atom, it is one of the three exceptions to the octet rule.


*Ex. He:He


While most other elements have to bond with octets. Such as Hydrogen, Carbon, and Nitrogen.


*H-C_=N:


Hydrogen bonds once with Carbon and Nitrogen and Carbon have to make an octet so the three lines (_=) and the same as the dot structure (:::) The two valence electrons on the left side of the Nitrogen atom cannot join the Carbon and Nitrogen bond because there is no way two atoms can have a quadruple bond.
Remember that each line equals to two electrons. So Nitrogen and Carbon have 8 electrons that they share, satisfying the octet rule.

Answer 2

The Lewis dot structure for H2 is very simple. It is 2 H atoms with a single bond between them.

Answer 3

H-N=N-H

put one lone pair on each nitrogen.

Answer 4

It is a Hydrogen- Oxygen covalent bond.
