Which best describes why nh4+ can form an ionic bond with cl–?

its outermost shell gains one or more electrons from cl–.
its positive charge is attracted to the negative charge of cl–.
it has a negative charge that is spread over the entire ion.
it has a nitrogen atom that is strongly attracted to cl–.

Answer;

Its positive charge is attracted to the negative charge of Cl–.

Explanation;

-Ionic bond is a type of bond that involves complete transfer of electrons between atoms. This type of bonds generates two oppositely charge ions, that is the cation (positively charged ion) and the anion (negatively charged ion).

-Ionic bond or electrovalent bond thus results from the electrostatic attraction between these opposite charged ions in a chemical compound.
