Which term describes a group of atoms that are chemically combined and have a neutral charge?

The term that describes a group of atoms that are chemically combined and have a neutral charge is compounds. Compounds form when two or more different types of atoms bond together through chemical means, resulting in a substance with properties distinct from the individual elements that constitute it. Crucially, this chemical bonding leads to a neutral overall charge as the atoms combine in ratios that balance their respective charges, whether they are ions or neutral atoms.

For example, when hydrogen and oxygen atoms combine to form water, they do so in a way that balances the positive charge of hydrogen with the negative charge of oxygen, resulting in a stable, neutral compound.

In contrast, elements are pure substances made up of only one type of atom and cannot be broken down into simpler substances through chemical reactions. Mixtures consist of two or more substances that are not chemically combined, and thus, they maintain their individual properties. Solutions are specific types of mixtures where one substance is dissolved in another, typically involving a solvent and solute, but do not result in the creation of a new substance with distinct properties.
