If we have a 3 valence electrons, the "A" charge will be either +3 or -5 for a full octet, and 6 valence electrons in "B" atoms will most likely result in acquisition of additional electrons (2) for an octet and relative charge of -2. Thus, "A" will be the positive ion, at +3
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom

A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−
