What is the periodic table?
The periodic table is a list where the various chemical elements that exist on the planet are kept . In it are those that have been discovered so far, identified by names and specific nomenclatures .
Everything dates from the era of the big bang better known as the bing bang . This explosion triggered thousands and thousands of reactions, generating in turn millions of separations of particles that divided and joined to form new elements.
This expansion and subsequent cooling after the great explosion gave rise to the activation process of multiple elementary particles, among which we can mention neutrons, protons and electrons.
- They are sorted by groups.
- They are in vertical columns within the table.
- The horizontal rows are called periods.
- Similar items are close to each other.
- Manage diversity in information.
- The elements are expressed with letters and abbreviations.
- Their respective atomic numbers are included in them.
- Express the atomic number.
- Provides information regarding atomic mass.
- Express the mass number of each element.
- They are sorted by: noble gases, metals, nonmetals, and metalloids.
The periodic table is divided into:
The order of the periodic table is done by “periods”, these periods are the rows of the periodic table.
These groups are made up of the elements that have similarity between them.
It is the number added to each element and they are ordered according to the number of protons contained per element.
Mass of elements
Denomination established based on the protons and neutrons of the nucleus of each element.
The colors are used to separate the types of elements that exist and are yellow, orange, green, blue, red, purple and lilac.
It refers to the number or quantity of electrons that an atom has at an energy level.
