Atoms with full valence electron shells are chemically stable. most noble gases have eight valence electrons. so, one model for chemical bonding is the octet rule. this states that atoms will or electrons in order to reach the more stable arrangement of eight electrons in their valence shells. a) lose, gain b) conduct, share c) transfer, share d) conduct, transfer

A) Lose, Gain

Explanation:

Octet is a game plan of an iota where the peripheral shell is filled by 8 electrons. So as to achieve octet , the components either lose or gain electrons relying on their reactivity , number of valence electrons and different variables.

For a metal : A non - metal increases electrons to finish octet. Eight electrons fill the valence level for every single respectable gas, with the exception of helium, which has two electrons in its full valence level.

answer; i believe that the correct answer is (decreased)

south, because if you took a map you would see texas is directly in the middle of east and west, but it is also downwards towards mexico, therefore it is south
