Question

using the
as\ idea, how many electrons are
eeded\ for the compound h₂s? 8 12 24

Explanation:

Step1: Determine the number of atoms

In \(H_2S\), there are 2 hydrogen (\(H\)) atoms and 1 sulfur (\(S\)) atom.

Step2: Calculate electrons needed for each atom

• Hydrogen (\(H\)): Each \(H\) atom needs 2 electrons (duet rule). For 2 \(H\) atoms, \(2\times2 = 4\) electrons.
• Sulfur (\(S\)): Each \(S\) atom needs 8 electrons (octet rule). So, 1 \(S\) atom needs \(1\times8=8\) electrons.

Step3: Sum up the electrons

Total electrons needed \(=4 + 8=12\)

Answer:

12
