Why don’t these gases tend to form chemical bonds? a. they have 8 electrons in their outer shell and don't need more to be stable. b. they don't have any electronsneed an answer. no guessing.

If you’re talking about noble gases, the answer would be A. Since noble gases already have 8 electrons, they don’t tend to form chemical bonds. And elements need just 8 electrons on there shells to be stable.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
