What are the two types of chemical bonds?

• A. Covalent and ionic bonds
• B. Metallic and Hydrogen bonds
• C. Ionic and metallic bonds
• D. Polar and nonpolar bonds

Answer: (A)

Atoms bond to achieve a stable electron configuration in two main ways: by sharing electrons or by transferring them. Covalent bonds form when atoms share one or more pairs of electrons, typically between nonmetals, so each atom can fill its outer shell. The sharing can be equal (nonpolar) or unequal (polar) depending on how strongly each atom attracts the shared electrons. Ionic bonds form when one atom donates electrons to another—usually a metal to a nonmetal—creating oppositely charged ions that attract each other strongly. There are other bonding interactions, like metallic bonds and hydrogen bonds, but the two fundamental categories describing how atoms connect to form most compounds are covalent and ionic.
