The chemical formula of methylamine is CH₃NH₂. How many valence electrons are associated with a molecule of methylamine?

Question

Quizplus · Accepted Answer

Methylamine has the chemical formula CH3NH2. Counting the valence electrons: Carbon (C) has 4, each Hydrogen (H) has 1 (and there are 3 H atoms in the methyl group and 2 H atoms bonded to N), and Nitrogen (N) has 5. Adding these gives 4 (from C) + 3*1 (from the 3 H in the methyl group) + 2*1 (from the 2 H bonded to N) + 5 (from N) = 14 valence electrons.
