Question

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

Explanation:

Step1: Determine valence electrons for each atom

Hydrogen (\(H\)) has \(1\) valence electron. Oxygen (\(O\)) has \(6\) valence electrons.

Step2: Calculate total valence electrons

In \(H_2O\), there are \(2\) \(H\) atoms and \(1\) \(O\) atom. Total valence electrons \(= (2\times1)+6\)
