What Is The Difference Between Elements, Atoms, Molecules And Compounds?

An element is more than one atom(explained further)of the same element chemically joined.In other words all atoms are the same.A compound is more than 2 or more elements chemically joined.An atom is the most smallest building block of matter.For e.g. Gold has gold atoms,silver has silver atoms, or steel has steel atoms.Since they have a lot of atoms that are the same,they are ELEMENTS.They are seen on the periodic table,created by russian Dmitri Mendeleev.Lastly a molecule is more than one atom chemically joined.If you need more help with your  english or science,send me questions that you have doubts about on Blurtit I am in 7th grade.I'm happy to help!!!

Elements are made up of atoms.
Compounds are made up of two (2) or more elements.

To understand the difference between them it is very important to understand what are the fundamental materials which make up a substance. An element is a substance which cannot be spilt into two or more simpler substance by any sort of chemical means. They are made up of particles which can either be atoms, molecules or ions.

An atom is the smallest particle that can take part in a chemical change. They are extremely small, about 10-10 meter in size.
Now coming to the explanation of molecules. A molecule is a smallest particle of a compound which is formed of a group of atoms. The atoms in a molecule are shown by a chemical formula.
A compound on the other hand is defined as a pure substance consisting of similar type of molecules which can be made up of different elements.

Water is the most common example of a compound. A water molecule is made up of three atoms in total out of which two are hydrogen and one is oxygen. Methane gas has molecules with one carbon and four hydrogen atoms. Carbon dioxide has molecules which contain one carbon and two oxygen atoms. All these are various examples of molecules which are combined together to form compounds.

Atoms are made out of electrons, neutrons, and protons. The important difference between an atom and a molecule is that an atom has only one nucleus (ball of protons and neutrons at the center), but a molecule has more than one because a molecule is two or more atoms stuck together.  There are different types of atoms and we call these types elements. We tell which element an atom is by how many protons it has. Hydrogen has one proton, Helium has two, and so on.

An element is a pure substance that can contain only one only one kind of atom while a compounds is a pure substances made up of atom of two or more different element join by chemical bonds.
Atom and molecule are very similar. They are the smallest unit of a substance that keep all the physical and chemical properties of that substance.

A compound contains atoms of two or more different elements

Show me 10 differend element and atom

The difference is that an element contains 1 type of atom and compounds are a bunch of atoms together.
