Options: 1. Atoms 2. Molecules<\/p>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-1-color\">The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n<p>The smallest unit of a compound is a <strong>molecule<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>A compound is a substance made up of two or more different elements that are chemically bonded. The smallest unit of a compound is a molecule because it consists of two or more atoms bonded together in a specific arrangement. These atoms in the molecule are connected by chemical bonds, which can either be covalent (sharing of electrons) or ionic (transfer of electrons).<\/p>\n\n\n\n<p>In contrast, an <strong>atom<\/strong> is the smallest unit of an element. It consists of a nucleus (containing protons and neutrons) and electrons that orbit around the nucleus. While an atom is the smallest building block of matter, it does not represent a compound on its own. When atoms of different elements bond together in fixed ratios, they form <strong>molecules<\/strong> of a compound. For example, water (H\u2082O) is a compound made up of two hydrogen atoms and one oxygen atom. In this case, the water molecule is the smallest unit of the compound.<\/p>\n\n\n\n<p>Moreover, the molecular structure of a compound determines its chemical and physical properties. For example, a water molecule\u2019s unique structure (H\u2082O) gives it properties like surface tension and the ability to dissolve many substances, which would not be the case if the compound were just a collection of individual atoms.<\/p>\n\n\n\n<p>So, the smallest unit of a compound is a <strong>molecule<\/strong>, which is composed of atoms chemically bonded together.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-597.jpeg\" alt=\"\" class=\"wp-image-245143\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Which is the smallest unit of a compound?
