Element, Compound, Atom, Molecule

Front

What is a molecule?

Back

A molecule is formed when two or more atoms bond together. For example, water (H2O) is a molecule made of two hydrogen atoms and one oxygen atom.

Front

What is the term for combining 2 or more atoms together?

Back

The term is 'molecule.' When two or more atoms bond, they create a molecule.

Front

What is an element?

Back

An element is a pure substance that consists of only one type of atom. For example, oxygen (O) and gold (Au) are elements.

Front

What is a compound?

Back

A compound is a substance formed when two or more different elements bond together. For example, carbon dioxide (CO2) is a compound made of carbon and oxygen.

Front

What is an atom?

Back

An atom is the smallest unit of matter that retains the properties of an element. It consists of protons, neutrons, and electrons.

Front

What is the difference between an element and a compound?

Back

An element is made of one type of atom, while a compound is made of two or more different types of atoms bonded together.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded. For example, a salad is a mixture of different vegetables.

Front

What is a chemical bond?

Back

A chemical bond is the force that holds atoms together in a molecule or compound. There are different types of bonds, such as ionic and covalent bonds.

Front

What is a proton?

Back

A proton is a positively charged particle found in the nucleus of an atom. The number of protons determines the element's identity.

Front

What is a neutron?

Back

A neutron is a neutral particle found in the nucleus of an atom. Neutrons contribute to the atomic mass but do not affect the charge.
