sodium and helium
Two or more elements combined chemically is a compound and the smallest unit is a molecule.
When elements combine chemically, they form a compound. A compound is a substance made up of two or more different elements that are chemically bonded together in a fixed ratio. Each compound has its own unique set of physical and chemical properties.
When atoms of two different elements chemically combine, they produce a compound. Such compounds include sodium chlorine, hydrogen fluorine, and barium sulfide. Note that if the elements are same, the result is a polyatomic element, not a compound.
When two elements chemically combine, they form a compound. A compound is a substance composed of two or more elements that are chemically bonded together in a fixed ratio. This bonding results in a new substance with properties different from those of the individual elements.
Yes, compounds are chemically bonded together. Compounds are formed when two or more different elements chemically combine to form a new substance with unique properties. The bonding can involve ionic, covalent, or metallic bonds depending on the elements involved.
These elements will not combine chemically.
