Verified step by step guidance1
Identify the central atom in the cation NH4+. In this case, nitrogen (N) is the central atom.
Determine the total number of valence electrons available. Nitrogen has 5 valence electrons, and each hydrogen has 1 valence electron. Since NH4+ is a cation with a +1 charge, subtract one electron from the total count.
Arrange the hydrogen atoms around the nitrogen atom and form single bonds between the nitrogen and each hydrogen. Each bond represents a pair of shared electrons.
Ensure that the nitrogen atom has a complete octet. In this case, nitrogen will have 8 electrons around it, satisfying the octet rule.
Place the entire structure within brackets and indicate the positive charge outside the brackets to represent the cation NH4+.
