Explanation:

Step1: Identify ionic compounds

Ionic compounds are formed between metals and non - metals.

• \(SrCl_{2}\) is formed from \(Sr^{2 +}\) (metal ion) and \(Cl^{-}\) (non - metal ion).
• \(K_{2}O\) is formed from \(K^{+}\) (metal ion) and \(O^{2 -}\) (non - metal ion).
• \(CaO\) is formed from \(Ca^{2+}\) (metal ion) and \(O^{2 -}\) (non - metal ion).

Step2: Identify covalent compounds

Covalent compounds are formed between non - metals.

• \(NO_{2}\) is formed between \(N\) (non - metal) and \(O\) (non - metal).
• \(O_{2}\) is formed between two \(O\) (non - metal) atoms.
• \(C_{6}H_{12}O_{6}\) is formed between \(C\) (non - metal), \(H\) (non - metal) and \(O\) (non - metal).

Step3: Identify metallic compound

Metallic compounds are made of metal atoms.

• \(Zn\) is a metal.

Answer:

Compound	Type
\(O_{2}\)	Covalent
\(Zn\)	Metallic
\(SrCl_{2}\)	Ionic
\(K_{2}O\)	Ionic
\(C_{6}H_{12}O_{6}\)	Covalent
\(CaO\)	Ionic
