An atom with a valence of 3 has how many electrons?
If an atom has a valence of 3, that means it forms three covalent bondsAs such, it either has three valence electrons (like boron or aluminum), or five valence electrons (like nitrogen, and sometimes phosphorous)The atom's total number of electrons will depend on its atomic number; boron has five electrons total, aluminum has 13, nitrogen has 7, and phosphorous has 15Since only valence electrons participate in bonding, we typically aren't interested in inner shell electrons, though.
