They form a compound.
Three elements chemically bonded together would form a compound.
They are bonded together via chemical bond and form compounds.
Compound !!
Two or more substances mixed together but not chemically combined form a mixture.
Many elements are found in nature in molecular form - two or more atoms (of the same type of element) are bonded together. Oxygen, for example, is most commonly found in its molecular form "O2" (two oxygen atoms chemically bonded together).
compound
When atoms of more than one element chemically bonded together, they form a molecule. In some contexts, the you might answer that they form a compound.
Molecule if they are chemically bonded, cluster if not. J Ayres
Two or more elements that are chemically bonded form a molecule of a chemical compound. This is the simple and direct answer to a good basic chemistry question. A molecule. However, if the chemical bond is ionic (like in a salt), it isn't called a molecule, but instead a compound. There are no salt molecules!
Carbon dioxide is a covalently bonded compound, because two (or more) different elements have chemically bonded to form the completely new substance.
Two or more atoms of different elements joined together form a compound. If it is a metal and non-metal (for example sodium and chlorine), they are ionically bonded. If it is two non-metals (for example methane is carbon and hydrogen), they are covalently bonded.
When two glucose molecules are chemically bonded together, they form a water molecule and sugar maltose. This process is called dehydration synthesis.
