Question

using the
as\ idea, how many electrons are \available\ for the compound cbr4? n = 40

Explanation:

Step1: Determine the number of valence electrons for each atom

• Carbon (\(C\)) has \(4\) valence electrons.
• Bromine (\(Br\)) has \(7\) valence electrons. There are \(4\) \(Br\) atoms in \(CBr_4\).

Step2: Calculate the total number of valence electrons (\(A\))

$$A=4+(4\times7)=4 + 28=32$$

Answer:

\(32\)
