Question

using the
as\ idea, how many electrons are \shared\ for the compound cbr4?
n = 40,
a = 32
8
72
4

Explanation:

Step1: Recall the formula for shared electrons

The formula for the number of shared electrons \(S\) using the NAS idea is \(S = N - A\), where \(N\) is the total number of valence electrons if each atom had an octet (or duet for hydrogen) and \(A\) is the total number of valence electrons from the atoms in the molecule.

Step2: Substitute the given values into the formula

Given \(N = 40\) and \(A=32\), we substitute these values into the formula \(S=N - A\).

$$S=40 - 32$$

$$S = 8$$

Answer:

\(8\)
