AlCl₃ is an ionic compound
Further explanation
Atoms have different stability. Unstable atomic atoms will try to form stable electron configurations like those of noble gases. Where noble gases have the number of outer electrons 2 or 8
The formation of electron configurations such as noble gases can be done by sharing electrons with covalent bonds or hand over electrons with ionic bonds
Generally, ionic bonds occur in metal and nonmetallic elements. Metal elements have low ionization energy and non-metallic elements have a high electron affinity
While covalent bonds occur because of the use of shared electrons. In general, this bond occurs between nonmetallic elements, which have the same electron attraction
We see the answer choices available
Between H elements that need 1 electron (duplet, to be stable on He element) and O element that requires 2 electrons (octet, so that it is stable on Ne elements) electron sharing occurs so that it includes covalent bonds
Between P elements that require 3 electrons and O which require 2 electrons, electron sharing occurs so that they include covalent bonds
Al element will release 3 electrons (according to the stable configuration element Ne). to be submitted to Cl element which requires 1 electron (according to the stable configuration of Ar elements)
So ion bonds occur
