Four students presented different analogies to describe the formation of an ionic bond.

Student A: A tug of war between seven middle school students and a high school student

Student B: A small dog and a big dog tugging at a bone with equal strength

Student C: Two neighbors carpooling to work

Student D: A group of high school students reading from the same book in the library

Which student presented a correct analogy?

A

B

C

D

Answer: The correct analogy is described by the student A.

Explanation:

Ionic bond is defined as the complete transfer of electrons from one atom to another atom. The atom which looses electrons is electropositive and atom which gains electron is electronegative atom.

The correct analogy is described by the student A.

In tug of war side with more number of individuals will able to pull the rope towards itself easily. When tug of war between the seven students of middle school and high school student.

The net force of pull exerted will more by the side where 7 students are present and they will able to pull the rope towards their side. On basis of this we can consider the group of 7 student as electronegative atom and single student on the other side as electropositive atom. Hence, describing the ionic bonding in a correct way.
