A Physical property is an aspect of matter that can be observed or measured without changing anything about it.

A Chemical property may only be observed by only changing the chemical identity of the substance.

It's the basic unit of a chemical element. It's a fundamental piece of matter. Matter is anything that can be touched physically. Everything in the universe except energy!!!! It's made of matter so that means everything in the universe is made up of atoms.
An atom itself is made up of three tiny kinds of particles called subatomic particles, protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud. The electrons carry a negative charge and the protons carry a positive charge. In a normal way (neutral) the number of protons and the number of electrons are equal. Often, but not always, the number of neutrons is the same, too.

That all matter is made up of tiny indivisible particles that are called atoms. According to the "modern" version the atoms of each element are effectively identical, but they differ from those of the other elements, and unite to form compounds in fixed proportions.

Common examples:
Wood, Sand, Brick, Ice

Physical Properties:
Has a definite shape and definite volume

Forces of Attraction (Intermolecular Forces)
The kinetic energies of the particles make up the substance. Kinetic energy tends to keep the particles moving apart. The attractive intermolecular forces between the particles tend to draw the particles together.

# data[].attributes.body
Matter can be classified as either a mixture or a pure substance. Mixtures can be of the same kind or diverse at character. Pure substances can be either elements or compounds. Pure Substances cant be separated into component parts by physical methods and follow the law of constant composition.

Common examples:
Propane, gaseous nitrogen, Water vape

Physical Properties:
They are easy to compress, they expand to fill their containers, and they occupy far more space than the liquids or solids from which they form.

Forces of Attraction (Intermolecular Forces)
Kinetic energy tends to keep the particles moving apart. The attractive Intermolecular forces between particles tend to draw the particles together.

Common examples:
Lighting, Welding Arcs, Gas clouds

Physical Properties:
Conductive, charged particles, electrical currents, generate magnetic fields. Makes up 99% of everything.

Forces of Attraction (Intermolecular Forces)
The particles of plasma basically all collide together and move in different directions.

Common examples:
Blood, Water, Wine,

Physical Properties:
Definite volume but no fixed shape

Forces of Attraction (Intermolecular Forces)
It is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds.
