Question

aria is learning about chemistry in school. she reads that water is made up of two hydrogen atoms and one oxygen atom bonded together. what is the term for a group of atoms bonded together, like in water? subscript a group of atoms bonded together coefficient basic unit of a chemical element

Explanation:

A molecule is defined as a group of atoms bonded together. In the context of water (\(H_2O\)), it consists of two hydrogen atoms and one oxygen atom bonded. The term "subscript" refers to the small number indicating the number of atoms of an element in a molecule (e.g., the "2" in \(H_2O\)). A coefficient is a number placed before a chemical formula (e.g., \(2H_2O\) means two water molecules). An element is a pure substance made of only one type of atom. Since the question asks for the term of a group of atoms bonded together, the key concept here is the definition of a molecule.

Answer:

A group of atoms bonded together is called a molecule.
