Question

1. calculate the number of valence electrons in water, h₂o. valence electrons

Explanation:

Step1: Determine valence electrons of H

Hydrogen (H) has 1 valence electron. There are 2 H atoms, so total for H: \(2\times1 = 2\).

Step2: Determine valence electrons of O

Oxygen (O) has 6 valence electrons. There is 1 O atom, so total for O: \(1\times6 = 6\).

Step3: Sum valence electrons

Add valence electrons of H and O: \(2 + 6 = 8\).

Answer:

8
