Question

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

a. Sulfur

b. Nitrogen

c. Calcium

d. Sodium

e. Gallium

Short answer

Group number and Lewis dot structure are:

(a) Sulfur: Group is $6A\left(16\right)$; Lewis structure

(b) Nitrogen: Group is $5A\left(15\right)$; Lewis structure

(c) Calcium: Group is $2A\left(2\right)$; Lewis structure

(d) Sodium: Group is $1A\left(1\right)$; Lewis structure

(e) Gallium: Group is $3A\left(13\right)$; Lewis structure

Step-by-step solution

Part (a) Step 1: Given Information

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

Part (a) Step 2: Explanation

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

Part (b) Step 1: Given Information

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

Part (b) Step 2: Explanation

Because group number of nitrogen is $5A\left(15\right)$, nitrogen has five valence electrons. So, Lewis dot structure of nitrogen is

Part (c) Step 1: Given Information

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

Part (c) Step 2: Explanation

Because group number of calcium is $2A\left(2\right)$,calcium has $2$valence electrons. So, Lewis dot structure of calcium is

Part (d) Step 1: Given Information

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

Part (d) Step 2: Explanation

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

Part (e) Step 1: Given Information

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

Part (e) Step 2: Explanation

Because group number of gallium is $3A\left(13\right)$, gallium has three valence electrons. So, Lewis dot structure of gallium is
