Question

Which two particles can form an ionic bond with each other?
A. a negative oxygen ion and a negative chlorine ion
B. a positive sodium ion and a positive magnesium ion
C. a positive calcium ion and a negative oxygen ion
D. a neutral fluorine atom and a negative sulfur io

Answer 1

Answer : The correct option is, (C) a positive calcium ion and a negative oxygen ion.

Explanation :

Ionic compound : ionic compounds are the compounds which are made up of positively charged cation and the negatively charged anion. The bond form between the cation and anion is known as ionic bond.

For example : NaCl, LiF, NaBr, etc.

In option C, a positive calcium ion combine with a negative oxygen ion to give calcium oxide. So, these two particles can form an ionic bond with each other.

While the other options A, B and D can not form an ionic bond with each other.

Therefore, the correct option is C.
