Question 1
On a piece of scratch paper, write out the Lewis Dot Diagram for each of the indicated
elements and then complete the following table for each:



1. Bromine
2. Silicon
3. Carbon
4. Sodium
5. Selenium



*Write number using number (1, 2, 3 etc.) rather than typing out the number (one,
two, three).
Answer

Element Total Number of The number of The number of The number of
Valence lone pairs of Unpaired bonds the atom
Electrons electrons Electrons will form



Br 7 3 1 1

Si 4 0 4 4

C 4 0 4 4

Na 1 0 1 1

Se 6 2 2 2


**Expert Rationale:**
The Lewis Dot Diagram for each atom visualizes their valence electrons based on
their group number in the periodic table. Bromine (Br, Group 17) has 7 valence
electrons, typically arranged as three lone pairs and one unpaired electron, allowing it
to form one bond. Silicon (Si, Group 14) and carbon (C, Group 14) each have 4
valence electrons, all unpaired, signifying the ability to form 4 bonds. Sodium (Na,
Group 1) has one valence electron, which is unpaired, so it generally forms one ionic
