Question #de0ab

Answer 1

Because chemical reaction occurs on the basis of transfer and sharing of the valence electrons between atoms........

Explanation:

And thus ions or elements that have their valence shells completely filled, tend to be unreactive. Likewise atoms in molecules react so that their valence electron shell is completely filled, and such process involves a chemical reaction.....

The common ions, `Na^(+), Mg^(2+), Al^(3+), N^(3-), O^(2-), X^(-)` ARE ALL isoelectronic with the last or the next Noble Gas......i.e. `"neon"` or `"argon"`.......Of course, here the net charge on the ion means that they commonly occur as ionic species with their charge complemented by ions of equal and opposite electric charge.
