Answer 2

Answer:

lewis dot diagram for the following a.Hydrogen (H2) b.water( H2O) c.Carbon dioxide (CO2 ) d.Methane( CH4) e. Lifthium Fluride ( LiF)

Explanation:Rules to write Lewis dot diagram

1.Find the valence electrons of the atoms

2.Satisfy the electrons with surrounding atoms and draw the bonds as line (➖)

3.Leave the remaining electrons as dot(•)

Lewis dot diagram for

1.Hydrogen(H2)

Valence electrons on each hydrogen is one and two hydrogens are satisfied by one bond ( contains two electrons)

H ➖H

2.Water(HO)

Valence electrons on each hydrogen is one and valence electrons on oxygen is six. Two electrons are satisfied by two bonds and remaining electrons are represented as dot(•).

••

H ➖O ➖H

••

3.Carbondioxide(CO2)

Valence electrons on carbon is four and on oxygen is six. Carbon forms two bonds with each of oxygen. Remaining four electrons on oxygen are represented as dot(•)

•• ••

O = C = O

•• ••

4.Methane(CH4)

Valence electrons on hydrogen is one and on carbon is four. Carbon forms four bonds with all four hydrogens.

H

5.Lithium fluoride (LiF)

Valence electrons on Lithium form one bond with Fluorine containing seven valence electrons. Remaining six electrons are represented as dots(•)
