Final answer:
Dihydrogen sulfide is identified as a covalent compound because it is composed of non-metal elements, hydrogen and sulfur, which share electrons.
Step-by-step explanation:
Dihydrogen sulfide is a covalent compound. This compound consists of hydrogen and sulfur. Both hydrogen and sulfur are non-metals, and when non-metals combine, they typically form covalent bonds as they share electrons to achieve a full valence shell. In contrast, ionic bonds form between metals and non-metals, where electrons are transferred from the metal to the non-metal, creating ions with positive and negative charges.
