How is NH3 a base?
because nitrogen contains a lone pair
Generally, molecules with lone pairs are more likely to donate that electron pair, which is the Lewis definition of a base. Therefore, molecules with more lone pairs are more likely to be bases since they have more electrons to donate.
A lewis definition of a base is a proton donor so N, having a lone pair is likely to give that pair away therefore making it a base.
A base is a molecule that donates electrons, meaning the molecule will usually have one or more lone electron pairs. In this case, the N in NH3 has a lone electron pair, so it is a base.
because it has one lone pair its most likely going to donate it and that what considers a base.
