This depends on the type of reaction. If one element reacts with another element, then it is a formation reaction. ex. Na + Cl ---> NaCl If a compound reacts with a compound, it is a double replacement reaction. ex. NaCl + MgO ---> Na2O + MgCl2
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 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.
When they combine chemically, they form compounds, which can have very different chemical properties than the constituent elements.If they are combined physically, they only form mixtures, alloys, or colloids.
When you chemically combine chlorine and sodium, you get sodium chloride, which is commonly known as table salt. Sodium donates an electron to chlorine, forming an ionic bond between the two elements.

This is called a compound.

a compound
When two or more materials combine chemically, they from a substance. When two or more materials combine and they do not react with each other, they form a mixture.
Two or more elements combined chemically is a compound and the smallest unit is a molecule.
Molecule
Hydrogen and Oxygen.
This is called a compound. Such as NaCl [Sodium Chloride(Table Salt)].
