BH3 has 3 valence electrons. Boron has 3 valence electrons and each hydrogen contributes 1 valence electron.
BH3 is a strange molecule since Boron doesn't have an octet rule, but rather a sexet rule meaning 6 valence electrons as opposed to 8 for it's valence shell. BH3 is a metal, Boron, and three nonmetals, Hydrogen, so it is an ionic bond.
BH3 does not exhibit typical covalent or ionic bonds due to the lack of electrons in boron's valence shell. Instead, BH3 forms coordinate covalent bonds where a shared pair of electrons come from a donor atom with a lone pair.
Indium has 3 valence electrons.
8 valence electrons- 1s22s2p63s2p6
There are 3 valence electrons in an atom of aluminium.

Zinc has two valence electrons.
Aluminum has 3 valence electrons.
5 valence electrons.
Beryllium has two valence electrons.
3 valence electrons
There are 3 valence electrons in an atom of aluminium.
There are no valence electrons.
In the Lewis dot structure for BH3, there should be 3 bonds drawn. Each hydrogen atom forms a single covalent bond with the boron atom. Boron has three valence electrons, so it can form three bonds with the hydrogen atoms.
