Question

1. calculate the number of valence electrons in formaldehyde, ch₂o. valence electrons

Explanation:

Step1: Determine valence electrons per atom

Carbon (C) has 4 valence electrons, hydrogen (H) has 1, oxygen (O) has 6.

Step2: Count atoms in \(CH_2O\)

1 C, 2 H, 1 O.

Step3: Calculate total valence electrons

Total = (4×1) + (1×2) + (6×1) = 4 + 2 + 6 = 12.

Answer:

12
