Question

1. calculate the number of valence electrons in hydrogen cyanide, hcn. valence electrons

Explanation:

Step1: Determine valence electrons of each atom

Hydrogen (H) has 1 valence electron, Carbon (C) has 4 valence electrons, and Nitrogen (N) has 5 valence electrons.

Step2: Sum the valence electrons

To find the total number of valence electrons in HCN, we add the valence electrons of each atom: \(1 + 4 + 5 = 10\).

Answer:

10
