A compound
A moleule has more particles than an atom, since a molecule is made up of two or more atoms chemically bonded together. An atom is the basic unit of an element, consisting of protons, neutrons, and electrons.
Something that isn't an element is a substance with more than one type of atom in. (e.g. a nickel atom and a silver atom). An substance that is an element has only on etype of atom in (e.g. only gold atoms, only iodine atoms).
Posibly. 'Substance' simply means there is something, without distinction as to the makeup of it.
atom
A compound.. like Water = H2O
These are called polyatomic ions.
The smallest part of a substance made from more than one atom that still retains the properties of the substance is a molecule. A molecule is a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
An element contains only one type of atoms. the substance which is made of more than one type of atom is called COMPOUND.Read more: Is_an_element_made_out_of_more_than_one_type_of_atom
