Antoine Lavoisier is widely regarded as the father of modern chemistry due to his groundbreaking work on combustion and the law of conservation of mass.

An atom is the basic unit of matter and consists of a nucleus containing protons and neutrons, surrounded by electrons.

The periodic table is a tabular arrangement of chemical elements, organized by their atomic number, electron configuration, and recurring chemical properties.

The law of conservation of mass states that the total mass of the reactants in a chemical reaction is equal to the total mass of the products.

An atom is the basic unit of an element, consisting of a nucleus containing protons and neutrons, surrounded by electrons. A molecule is a combination of two or more atoms held together by chemical bonds.

Chemistry plays a vital role in everyday life, as it is involved in the production of food, clothing, shelter, medicines, vaccines, energy, and transportation.
