he law of conservation of matter or principle of matter conservation states that the mass of an object or collection of objects never changes over time, no matter how the constituent parts rearrange themselves.

An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms

# data[].attributes.body
a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.

# data[].attributes.body
A substance which undergoes a physical reaction; changes its shape or the phase, remaining the substance as it is.

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties.

The Law of Conservation of Matter states that matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same.

Atoms are a source of nuclear energy

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

# data[].attributes.body
A physical reaction occurs when molecules undergo a molecular rearrangement to produce a physical change.
