Question

using the
as\ idea, how many electrons are
eeded\ for the compound cbr4? 32 24 40

Explanation:

Step1: Determine the number of atoms

In \(CBr_4\), there is 1 carbon (\(C\)) atom and 4 bromine (\(Br\)) atoms.

Step2: Calculate electrons needed for each atom

• Carbon (\(C\)) needs 8 electrons (to complete its octet).
• Each bromine (\(Br\)) atom needs 8 electrons. Since there are 4 \(Br\) atoms, total electrons for \(Br\) is \(4\times8 = 32\) electrons.

Step3: Sum up the electrons

Total electrons needed \(=8 + 32=40\)

Answer:

40
