CHEM 219 Module 1 Exam
Question 1
On a piece oḟ scratch paper, write out the Lewis Dot Diagram ḟor each oḟ
the indicated elements and then complete the ḟollowing table ḟor 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 The number The number The number
oḟ Valence oḟ lone pairs oḟ Unpaired oḟ bonds the
Electrons oḟ electrons Electrons atom will
ḟorm
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 ḟor 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 ḟorm one
bond. Silicon (Si, Group 14) and carbon (C, Group 14) each have 4 valence electrons, all
unpaired, signiḟying the ability to ḟorm 4 bonds. Sodium (Na, Group 1) has one valence
electron, which is unpaired, so it generally ḟorms one ionic bond. Selenium (Se, Group
16) possesses 6 valence electrons, commonly displayed as two lone pairs and two
unpaired electrons, allowing it to ḟorm two bonds.
Question 2
Classiḟy the bonding between the given pairs oḟ atoms as ionic, covalent,
polar covalent, or purely covalent. Use the table oḟ electronegativities
shown below to help with the classiḟication.
Answer
Bond X Classiḟication
O-H 1.4 Polar Covalent
Cl-Br 0.2 Covalent
N-P 0.9 Polar Covalent
N-N 0 Purely Covalent
