What is the definition of an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is the difference between an ion and an atom?

Back

An ion is an atom that has gained or lost one or more electrons, resulting in a net charge, while an atom is neutral.

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.
