Question

For the hypothetical compound AX2 which statement is true

Answer 1

Answer:

D. A is a metal from group 2, and X is a nonmetal from group 7

Answer 2

Answer: Option (D) is the correct answer.

Explanation:

Metals are the species which tend to lose electrons in order to attain stability. When a metal loses one electron then it acquires a +1 charge and if a metal loses 2 electrons then it acquires a +2 charge and so on.

On the other hand, non-metals are the species which tend to gain electrons in order to attain stability.

When one electron is gained by a non-metal then it acquires a -1 charge and when two electrons are gained by a non-metal then it acquires a -2 charge and so on.

For example, a metal of group 2 will have a +2 charge in ionic form and when it combines with a non metal who needs to gain one or two electrons then the compound formed will be $AX_{2}$.

As $MgCl_{2}$ can be assumed in place of $AX_{2}$.

Thus, we can conclude that the statement A is a metal from group 2, and X is a nonmetal from group 7.
