What happens when the compound HCl is formed?
A) Hydrogen transfers two electrons to chlorine.
B) Hydrogen receives two electrons from chlorine.
C) Hydrogen forms an ion with −1 charge; chlorine forms an ion with +1 charge.
D) Hydrogen forms an ion with +1 charge; chlorine forms an ion with −1 charge.

Answer :

Answer: The correct answer is Option D.

Explanation:

Ionic compounds are defined as the compounds which are formed by the complete transfer of electrons from one atom to another atom. In these compounds, oppositely charged ions are attracted towards each other to form a compound.

Hydrogen is the 1st element of the periodic table having 1 electron. The electronic configuration of this element is [tex]1s^1[/tex]

This will loose 1 electron to form [tex]H^+[/tex] ion.

Chlorine is the 17th element of the periodic table having 17 electrons. The electronic configuration of this element is [tex]1s^22s^22p^63s^23p^5[/tex]

This will gain 1 electron to form [tex]Cl^{-}[/tex] ion.

To form HCl compound, 1 hydrogen ion is needed to neutralize the charge on chlorine ion.

Hence, the correct answer is Option D.
