Energy & Matter.

i read that Matter is an Energy Form.

Matter is made of Atoms.

Energy has many forms, is also made of Atoms & Free Electrons.

Energy Forms include:
- Potential Energy,
- Kinetic Energy,
- Chemical Energy,
- Mass Energy, as expressed in Einstein's famous equation: E = mc²,
- ...


Atoms & Free Electrons.

Atoms are made of Nucleus & Electrons orbiting around Nuclei.

Nucleus is made of Protons & Neutrons.

Protons give atom a positive charge, electrons give negative charge - when these neutralize each other, atom's charge is zero, a neutral charge.

An ion is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge.

Free electron is an electron that is not attached to an atom or ion or molecule but is free to move under the influence of an electric field.


Atoms & Molecules.

An atom is smallest particle in an element that has the properties of the element. It is not possible to breakdown the atom further retaining the properties of the element.

Molecules are formed by the combination of two or more atoms. Unlike atoms, molecules can be subdivided to individual atoms. The atoms are bonded together in a molecule.


Physical Values.

Atom's mass ranges from 1.67 × 10⁻²⁷ to 4.52 × 10⁻²⁵ kg.

Atoms' size range from 0.1 to 0.5 nanometers in width (1 nm = 10^-9 m).

Electron's mass is 9.10938291(40)×10⁻³¹ kg.

Electron's charge, Elementary Negative Charge, is equal to approximately: -1.6021766208(98)×10⁻¹⁹ coulombs.

Proton's mass is approximately 1.672621777(74)×10⁻²⁷ kg.

Proton's charge is also Elementary Charge, Elementary Positive Charge, is equal to approximately 1.6021766208(98)×10⁻¹⁹ coulombs, a negation of electron's charge.

Neutron's mass is approximately 1.674927471(21)×10⁻²⁷ kg.

Neutron's charge is 0.


it's hard to define subatomic particle's sizes in terms of 'balls with size'.

Electron size depends on how we perceive atom, if it's a 'small ball of energy', then it's approximately 1 femtometer (1 fm = 10^-15 m).
