Write the group number and draw the Lewis symbol for each of the following elements:

a. carbon

b. oxygen

c. argon

d. lithium

e. chlorine

We need to find the group number and Lewis structure for carbon.

Because group number of carbon is $4A\left(14\right)$,carbon has four valence electrons. So, Lewis dot structure of carbon is

We need to find the group number and Lewis structure for oxygen .

Because group number of oxygen is $6A\left(16\right)$, oxygen has six valence electrons. So, Lewis dot structure of oxygen is

We need to find the group number and Lewis structure for argon

Because group number of argon is $8A\left(18\right)$, argon has eight valence electrons. So, Lewis dot structure of argon is

We need to find the group number and Lewis structure for lithium

Because group number of lithium is $1A\left(1\right)$, lithium has one valence electrons. So, Lewis dot structure of lithium is

We need to find the group number and Lewis structure for chlorine .

Because group number of is chlorine $7A\left(17\right)$, chlorine has seven valence electrons. So, Lewis dot structure of chlorine is
