True.

Quick Scoop

Ionic compounds are usually formed between a metal (which loses electrons to form a cation) and a non-metal (which gains electrons to form an anion), so the statement is true in the context of typical school chemistry. Most introductory examples—like sodium chloride (NaCl), magnesium oxide (MgO), and calcium fluoride (CaF₂)—are all metal + non‑metal combinations.

Why the Statement Is “Usually” True

  • Metals tend to lose electrons easily, forming positively charged ions (cations).
  • Non‑metals tend to gain electrons, forming negatively charged ions (anions).
  • The electrostatic attraction between these opposite charges is what creates an ionic bond and thus an ionic compound.

So as a rule of thumb taught in most courses:

When a metal combines with a non‑metal, the compound is usually ionic.

Subtle Twist: “Usually” vs “Always”

  • The statement says “usually,” not “always,” and that wording is important and correct.
  • There are some edge cases and more complex bonding situations, but for typical classroom and exam questions, “ionic compound = metal + non‑metal” is the accepted idea.

Bottom line

For a true/false style question in a standard chemistry context, you can confidently mark:

True – ionic compounds are usually a combination of a metal and a non‑metal.
