Respuesta :

The answer to your question is Gallium, or GA. The trick is to always check if they are along the same vertical column. This indicates that they have the same Valence electrons, which is involved in all the bonding and define the electronegative status of the atom.

Remark

I can't understand why this was reported. It's a perfectly straight forward question, unless someone recognized it as part of a test.

I know that the answer is supposed to be Ga, but in many ways Boron resembles Carbon than it does Ga. Be that as it may, the answer you want is Ga.
