How are metallic and nonmetallic elements generally combined?

Metallic and nonmetallic elements are generally combined to form ionic and covalent compounds due to their distinct properties. Metallic elements typically possess high conductivity and malleability, and they tend to lose electrons in chemical reactions, forming positively charged ions (cations). Nonmetallic elements, on the other hand, usually gain electrons to form negatively charged ions (anions) or share electrons during bonding.

In ionic compounds, the transfer of electrons from metals to nonmetals leads to the formation of oppositely charged ions that attract each other, creating a strong electrostatic force that holds the compound together. Sodium chloride (table salt) is a classic example where sodium (a metal) donates an electron to chlorine (a nonmetal), resulting in an ionic bond.

In covalent compounds, nonmetals can share electrons with other nonmetals. However, when a metallic element is involved with nonmetals, such as in the case of hybrid compounds or metalloids, the nature of bonding can vary.

The other options present limiting scenarios that do not accurately describe the versatility of metallic and nonmetallic combinations. Ionic and covalent bonds can occur in various phases, including solid, liquid, and gas, and do not depend solely on
