H₂CO₃, known as carbonic acid, is a molecule composed of atoms. It consists of two hydrogen atoms, one carbon atom, and three oxygen atoms. As a compound, it is not an element on the Periodic Table but rather a molecular substance formed from different elements.
an atom
The atom of an element is smaller than a molecule.
"element" (2 make up a molecule)
One carbon atom is an element. You must have two or more atoms to make a molecule.
An element, atom, crystal, compound, and molecule are all forms of matter.
An atom for an ELEMENT and a molecule for a COMPOUND.
There is one atom of that element in the molecule.
An atom is the smallest unit of matter that retains the properties of an element. A molecule is a group of atoms bonded together. An element is a substance made up of only one type of atom.
A molecule of an element is a molecule made up of the same substance that can exist as an atom; for example, oxygen as O2.
Hydrogen, carbon and oxygen are the elements found in H2CO3
Phosphorus is an element that exists as individual atoms. It is not a molecule.
An atom is the smallest unit of matter that retains the properties of an element. An element is a pure substance made up of only one type of atom. A molecule is a group of atoms bonded together.
