Molecula

A molecule is the smallest part of matter that retains the properties of a material, and can be formed by a single atom (helium: He, or metals) or be polyatomic (such as water: H2O).

Atomo

An atom is the smallest unit of matter that retains all the chemical properties of an element.

two or more can form

Enlaces

A chemical bond is the force that binds atoms together to form chemical compounds

It is made up

Protones

Electrones

Positively charged particles are located in the nucleus of the atom.

They have a negative charge equal to 1 and negligible mass (two thousand times less than protons and neutrons).

Lewis

A molecule is the result of the combination of two or more atoms that share electrons with each other.

Octeto

It establishes that the ions of the different chemical elements found in the Periodic Table usually complete their last energy levels with 8 electrons.

Orbital

The orbital is the wave description of the size, shape, and orientation of a region of space available to an electron.

Funcion de trabajo

minimum energy that must be provided to an atom to release an electron from the surface of a given substance.

Valencia

the number of electrons it needs or has left over to complete its last level.

Numero cuantico

are numerical values ​​that describe and indicate the characteristics of the electrons of atoms.

Nivel de energia

fixed distances from the nucleus of an atom where electrons can be found.

Radiaccion

emission, propagation and transfer of energy in any medium in the form of electromagnetic waves or particles.

Foton

elementary particle that makes up light and the quantum of energy in the form of electromagnetic radiation, emitted or absorbed by matter.

Corrimiento copton

It consists of the increase in the wavelength of a photon when it collides with a free electron and loses part of its energy.
