ionic bond
metallic bond

1. choose the best answers using a periodic table. (see companion material attached.)

Explanation:

• For question 6: Sodium (Na) is a metal (loses electrons) and chlorine (Cl) is a non - metal (gains electrons). Ionic bonds form between metals and non - metals through the transfer of electrons. Metallic bonds are between metal atoms, and covalent bonds are between non - metals (sharing electrons).
• For question 7: Carbon (C) and oxygen (O) are both non - metals. Non - metals tend to form covalent bonds by sharing electrons. Ionic bonds are for metal - non - metal combinations, and metallic bonds are for metal - metal combinations.

Answer:

1. B. ionic bond
2. A. covalent bond
