It would be Li and F because Li has 3 electrons which means it has an unstable outer shell as it would have 1 electron in the outer shell, however, F has 9 electrons and it needs 1 more electron in its outer shell in order to become stable so it will be shared with Li
The main molecules present in the plasma membrane are<em><u> phospholipids</u></em>, those molecules are made of a polar, hydrophil end(glycerol with a phosphate group attached) and two non-polar, hydrophobe ends(two fatty acids rests). The cell identity is determined by <u><em>proteins </em></u>present in the membrane, a very important type of protein that determines the identity of a specific cell is called marker. The membrane fluidity is reduced by a lipid with a ring structure, <u><em>cholesterol</em></u>, this molecule belongs to a class of biomolecules called steroids.
