true/false statements

1. ionic bonds form when electrons transfer completely from one at to another, not shared.
2. covalent bonds usually occur between nonmetal atoms that sha electrons to fill outer shells.
3. metallic bonds involve delocalized electrons moving freely, no between just two atoms.

Explanation:

Step1: Break down each compound

List elements + subscript quantity, classify bond type (ionic: metal+nonmetal; covalent: nonmetal+nonmetal; metallic: metal+metal/alloy)

Step2: Evaluate true/false statements

Match to bond definitions, verify accuracy.

True/False Statements:

1. True: Ionic bonds form via full electron transfer (no sharing) between metals and nonmetals.
2. True: Covalent bonds form when nonmetals share electrons to fill valence shells.
3. True: Metallic bonds have delocalized "sea of electrons" that move freely across all metal atoms, not just two.
