Question

1. choose the best answers using a periodic table. which type of bond is expected between two cobalt (co) atoms. metallic bond ionic bond covalent bond 5. choose the best answers using a periodic table. which type of bond forms between potassium (k) and chlorine (cl) atoms? covalent bond ionic bond metallic bond

Explanation:

• For cobalt (Co) atoms: Cobalt is a metal. Metallic bonds occur between metal atoms. In metallic bonding, metal atoms share a "sea of electrons".
• For potassium (K) and chlorine (Cl) atoms: Potassium is a metal (loses electrons to form \(K^{+}\)) and chlorine is a non - metal (gains electrons to form \(Cl^{-}\)). Ionic bonds form between metals and non - metals through the transfer of electrons.

Answer:

1. metallic bond
2. ionic bond
