It is called a compound.
two or more atoms put together is called a molecule.
Two or more different atoms bonded together is called a compound.
Multiple atoms bonded together are called molecules.
Such a group of atoms is called a molecule.
Two or more atoms joined together form a molecule. You can't say compound because you do not specify that the atoms are of different elements. You can have a molecule of oxygen because two or three atoms of oxygen can couple together by themselves, but it is not a compound, it is a molecule of oxygen.
Two or more atoms joined together are called molecules. These molecules can be composed of the same type of atoms, known as elements, or different types of atoms, forming compounds.
It is called chemical bonding.
A molecule contains two or more atoms that are chemically bonded together. These atoms can be identical or different elements that come together to form a distinct structure with its own unique properties.
Fusion - but it would have to be two or more!
That would be called a Compound.
A molecule.
Molecules are made of more two or more atoms joined together. The atoms can be same or different elements. A single molecule is the smallest piece of matter.
