Question

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

Short answer

Group number and Lewis symbol for elements are:

Element	Group Number	Lewis Structure
Carbon	$4A\left(14\right)$
Oxygen	$6A\left(16\right)$
Argon	$8A\left(18\right)$
Lithium	$1A\left(1\right)$
Chlorine	$7A\left(17\right)$

Step-by-step solution

Part (a) Step 1: Given Information

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

Part (a) Step 2: Explanation

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

Part (b) Step 1: Given Information

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

Part (b) Step 2: Explanation

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

Part (c) Step 1: Given Information

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

Part (c) Step 2: Explanation

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

Part (d) Step 1: Given Information

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

Part (d) Step 2: Explanation

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

Part (e) Step 1: Given Information

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

Part (e) Step 2: Explanation

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