When we mix two different pure substances together, like this, it’s a mixture. This is now a mixture of the elements iron and sulfur. The different elements are not joined together.
A compound is a substance that contains two or more elements chemically combined in a fixed proportion. The elements carbon and hydrogen combine to form many different compounds. One of the simplest is called methane, in which there are always four times as many hydrogen atoms as carbon atoms.
Compound: two or more different atoms bonded together. Mixture: two or more different atoms together but not joined. Molecule: two particles (same or different) bonded together. Element: only 1 type of atom; this definition is applied to things both bonded and not to itself.
Compounds. A compound is a substance that contains atoms of two or more different elements, chemically joined together. For example, water is a compound of hydrogen and oxygen, chemically joined...

Compounds are made up of elements, which are pure substances with only one kind of atoms. Atoms of the elements form bondsto combine and make up a molecule of the compound. The compound contains a uniform distribution of these molecules. A compound has different physical and chemical characteristics than its component elements. It is not possible t...
The component elements of a compound can only be separated via a chemical reaction that breaks the atomic bonds that bind its molecules. The ingredients of a mixture may be separated by physical means like sedimentation or decantation.
Mixture - WikipediaCompounds - WikipediaExperiments to see how compounds and mixtures of iron and sulphide behave under various conditions - YouTubeMatter: Mixtures vs Compounds - YouTubeWhile the terms do overlap, they’re technically not the same. Compounds are two or more elements chemically combined in definite proportions by weight. Mixtures are two or more substances not chemically combined. Read on for a more thorough explanation of the properties of compounds and mixtures.

What happens when atoms from different elements are joined together?
A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together. Note that the two nitrogen atoms which comprise a nitrogen molecule move as a unit.
