Question

Why can’t molecules made from the same atom from ionic bonds?

Answer 1

Ответ:

because there are cations and anions:)

the same element can't have 2 different charges (I mean + and - charges)

Answer 2

Molecules made from the same type of atom typically do not form ionic bonds because ionic bonds are formed through the transfer of electrons from one atom to another. In an ionic bond, one atom loses electrons (forming a positively charged ion or cation), while the other atom gains those electrons (forming a negatively charged ion or anion). This electron transfer creates a strong electrostatic attraction between the oppositely charged ions, resulting in the formation of a stable ionic compound.

For molecules made from the same type of atom, there is no significant difference in electronegativity (the tendency of an atom to attract electrons) between the atoms involved. Ionic bonding typically occurs between elements with significantly different electronegativities, where one atom's ability to attract electrons is much stronger than the other's ability to hold onto them. In such cases, one atom can easily donate electrons to the other, resulting in the formation of ions.

When atoms of the same element are involved, their electronegativities are usually very similar, and neither atom has a significantly stronger tendency to gain or lose electrons. As a result, there isn't a strong driving force for electron transfer, and ionic bonds are not typically formed between identical atoms.

Instead, when identical atoms bond, they often form covalent bonds. In covalent bonding, atoms share electrons to achieve a more stable electron configuration. This type of bonding is common among nonmetal elements that have similar electronegativities and can share electrons in a way that allows both atoms to achieve a more stable electronic configuration.

In summary, molecules made from the same type of atom usually do not form ionic bonds because the conditions required for ionic bonding, such as significantly different electronegativities, are not met in these cases. Instead, covalent bonds are more likely to be formed through the sharing of electrons between the atoms.
