What is a compound created by?
The answer is that compounds are formed when elements are joined and held together by strong forces called chemical bonds. These bonds involve the electrons that orbit the nucleus of the atom.
What elements can form a compound?
When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).
How compounds are formed is all about?
Compounds occur when two or more atoms combine into a pure substance. These can be broken down into their constituent atoms. In chemical reactions the atoms of the reactants interact to form new substances.
Can you make compounds?
While atoms of an element do exist alone, they often combine with other atoms to form compounds, the smallest quantity of which is referred to as a molecule. These molecules can be formed through either ionic, metallic, covalent or hydrogen bonding.
How do elements combine to form compounds?
Elements combine to form chemical compounds that are often divided into two categories. Metals often react with nonmetals to form ionic compounds. These compounds are composed of positive and negative ions formed by adding or subtracting electrons from neutral atoms and molecules.
What is the formation of compounds?
A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures, the substances present are not chemically bonded together.
What are some examples of compounds mixtures and elements?

What elements are molecules made of?
Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms. The atoms of certain elements readily bond with other atoms to form molecules. Examples of such elements are oxygen and chlorine.
