What are the two ways molecules can be formed?

When atoms bond to form molecules, electrons participate in two fundamental ways: they can be transferred from one atom to another, creating oppositely charged ions that attract each other, or they can be shared between atoms so that each can fill its outer shell. The first pathway leads to ionic bonds, the second to covalent bonds. Both mechanisms describe how atoms can stick together to form bonded structures, which is why this option is the best fit. The other ideas describe processes that aren’t about forming typical molecules: nuclear fusion is about changing nuclei, not chemical bonding; covalent bonding only ignores the ionic bonding route; and a metal lattice involves metallic bonding with delocalized electrons, which isn’t about discrete molecules.
