Which one of the following compounds is ionic?Group of answer choicesH2SO4SO2SCl2NaBrH2S

The ionic compound among the given options is NaBr.

Here's why:

1. H2SO4 (Sulfuric Acid) is a molecular compound. It consists of nonmetals (Hydrogen, Sulfur, and Oxygen) and forms through covalent bonding.

2. SO2 (Sulfur Dioxide) is also a molecular compound. It consists of nonmetals (Sulfur and Oxygen) and forms through covalent bonding.

3. SCl2 (Sulfur Dichloride) is another molecular compound. It consists of nonmetals (Sulfur and Chlorine) and forms through covalent bonding.

4. NaBr (Sodium Bromide) is an ionic compound. It consists of a metal (Sodium) and a nonmetal (Bromide). Ionic compounds form when a metal transfers one or more electrons to a nonmetal in an effort to fill its outer shell. This results in a positive ion (the metal) and a negative ion (the nonmetal). The opposite charges cause the ions to attract each other, forming an ionic bond.

5. H2S (Hydrogen Sulfide) is a molecular compound. It consists of nonmetals (Hydrogen and Sulfur) and forms through covalent bonding.
