Note that there is only one capitalized letter in the formula, s o it is an element
It means that you have one atom of each element in the formula
Oxygen is an element. This means that it is composed of only one kind of atom, and it takes two atoms of oxygen to make one molecule of oxygen. A compound is composed of more than one kind of element. A simple example is carbon dioxide which is composed of one atom of carbon and two atoms of oxygen. A mixture is composed of more than one kind of compound.
Iodine is an element, which means it is a pure substance made up of only one type of atom. It is found on the periodic table with the symbol "I" and atomic number 53.
Oxygen.The C in CO2 stands for Carbon, the O for oxygen and the 2 to say that there are two oxygen atoms in the carbon dioxide molecule. If there is no 2 or 3 or whatever next to the representation of the atom, this means that there is only one of that atom in the molecule
an element
an element or a molecule
element because it is made up of only one type of molecule
An element can be distinguished by only one atom of an element because it has significant properties, while a molecule has to be found by two atoms like O2 and H2.
An elemental molecule, like H2 or O2.
There is one atom of that element in the molecule.
Oxygen is an element in its own right, so it only contains one element: oxygen.
The term for matter made of only one type of element is "pure substance," while matter made of only one type of molecule is called a "pure compound."
A molecule can be either an element or a compound, depending on its composition. If a molecule consists of only one type of atom, it is an element. If a molecule is made up of two or more different types of atoms bonded together, it is a compound.
What is composed of only one type of molecule
There is one element only. Oxygen atom is there.
An example of a molecule that contains only one type of atom is a diatomic gas. Diatomic gases include Hydrogen, Oxygen and Nitrogen. Inert gases are not diatomic. A molecule of any element is made up of one type of atom. So carbon, hydrogen, oxygen and ozone molecules, among many others, are each made up of one type of atom. However the oxygen molecule is made of atoms that are different from those in the hydrogen molecule.
