Answer:
e. do both (a) and (b).
Explanation:
Covalent bond
This is another type of chemical bond, through which atoms can also have 8 electrons at their last energy level, and thus comply with the law of the octet.
The covalent bond is defined as the union of non-metal atoms to share their valence electrons, by means of electromagnetic attractive forces, mainly; Here atoms do not gain or lose their electrons, but share them in quantities of one, two, three and even four in various situations. The last electron layer of the atoms that bind together is intertwined or overlapping, forming the true molecules, contrary to what happens in the ionic bonds, in which the united atoms only approach each other to form true aggregates, instead of true molecules. In general, atoms of organic substances have this type of bond and, in addition, it is very common among atoms of the same class or species (Chlorine with Chlorine, Oxygen with Oxygen, Carbon with Carbon)
