🤓 Based on our data, we think this question is relevant for Professor Mohseni's class at East Tennessee State University.
Draw a Lewis structure for H3O+, Show all unshared electrons and the formal charges, if any. Assume that bonding follows the octet rule.
The central atom for H3O+ is O since Hs can't be a central atom. O has 2 bonding electrons and 2 lone pairs therefore a neutral oxygen atom has 2 atoms bonded on it with 2 lone pairs. A formal charge of positive indicates the use of a lone pair for bonding. This will make O bonded to 3 atoms with 1 lone pair of electrons.
