Which of the following compounds is ionic?Group of answer choicesMgCl2PF3HClCS2SO2

The ionic compound among the given options is MgCl2 (Magnesium Chloride).

Here's why:

Ionic compounds are formed between metals and non-metals. Metals are electropositive (they tend to lose electrons) and non-metals are electronegative (they tend to gain electrons). When a metal reacts with a non-metal, the metal loses electrons to form a positively charged ion (cation) and the non-metal gains those electrons to form a negatively charged ion (anion). The resulting compound is held together by the electrostatic forces of attraction between the oppositely charged ions, which is what we call an ionic bond.

Now, if we look at the given compounds:

1. MgCl2 (Magnesium Chloride): Magnesium (Mg) is a metal and Chlorine (Cl) is a non-metal. So, MgCl2 is an ionic compound.

2. PF3 (Phosphorus Trifluoride): Both Phosphorus (P) and Fluorine (F) are non-metals. So, PF3 is a covalent compound, not ionic.

3. HCl (Hydrogen Chloride): Both
