The law of conservation of mass (matter is neither created nor destroyed) was first clearly formulated by Antoine Lavoisier in 1789. However, Mikhail Lomonosov (1748) had previously expressed similar ideas and proved them in experiments.

Thomas Dalton.

This is part of Dalton's Atomic Theory. The theory stated that all matter consists of atoms, atoms cannot change their identity , the Law of Conservation of Matter (indestructible spheres), all atoms of one element are identical in mass and hold unique properties, and the Law of Definite Composition.

-Light is similar to matter (and waves) but consists of photons, not atoms.

-Atoms can change their identity via nuclear reactions.

-The Law of Conservation of Matter does not apply to many nuclear reactions, and atoms can lose or gain electrons.

-Atoms of one element can have different numbers of neutrons (isotopes) and thus different masses.

-Only the Law of Definite Composition holds true today.

The idea that matter cannot be created or destroyed is known as the conservation of mass. It was discovered by Antoine Lavoisier.

This is the law of mass conservation - Antoine Lavoisier, a French chemist is credited with the discovery; but many scientists had before some intutions and contributions.
