D, silicon and oxygen

Answer 1

Ionic bond is formed between a metal and a non metal

1)

A) None of Si and O are metal. So, it forms covalent bond

B) None of N and Cl are metal. So, it forms covalent bond

C) Ba is metal and O is non metal. So, it forms ionic bond

D) None of S and Cl are metal. So, it forms covalent bond

Answer: C

2)

A) None of S and F are metal. So, it forms covalent bond

B) Ca is metal and Cl is non metal. So, it forms ionic bond

C) None of P and O are metal. So, it forms covalent bond

D) None of Si and O are metal. So, it forms covalent bond

Answer: B
