Question

The Lewis dot model of a molecule is shown.

A visual diagram of a PCl3 molecule is shown. Phosphorous is the central atom with a horizontal line connecting to each of the three Chlorine atoms around it. Phosphorous has a pair of dots on it. Each of the three chlorine atoms have a pair of three dots on it.

Based on the model, which of the following is true?

The electronegativity difference between phosphorous and chlorine is greater than 1.7.
Each chlorine has three non-bonded pairs and one bonded pair of electrons.
Phosphorous has three non-bonded pairs and one bonded pair of electrons.
Phosphorous has three valence electrons in the outermost energy level.

Answer 1

Answer:

The answer is B, Each chlorine has three non-bonded pairs and one bonded pair of electrons.

Explanation:

I took the test :)

Answer 2

Each chlorine has three non-bonded pairs and one bonded pair of electrons. Hence, option B is correct.

What is an electron dot structure?

Lewis dot structures also called electron dot structures are diagrams that describe the chemical bonding between atoms in a molecule.

Phosphorous is the central atom with a horizontal line connecting to each of the three Chlorine atoms around it. Phosphorous has a pair of dots on it. Each of the three chlorine atoms has a pair of three dots on it.

Each chlorine has three non-bonded pairs and one bonded pair of electrons.

Hence, option B is correct.
