Periodic Table

 1. Introduction


In the world of science, the periodic table is an easily understood mapping that recognizes the order of elements. The table is organized into two main groups, those that have a positive number on one side and those with a negative number on the other. These groups are called groups A and B.
When it comes to having a home in the world of science, there are three elements that tend to get you more attention than they deserve: protons and neutrons. Groups A and B can be described as stable and unstable respectively. Protons make up most of the atoms in the world of matter, including hydrogen , carbon , nitrogen , oxygen , sulfur , phosphorus , calcium , sodium , potassium , magnesium and rubidium . Neutrons are very hard to find in nature but can be found in superheavy element such as carbon-12 or beryllium-7.
If you’re interested in chemistry, then you might want to start learning about these elements before moving onto periodicity topics you’re more likely to enjoy: oxygen (O), carbon (C), nitrogen (N), hydrogen (H), fluorine (F), neon (Ne) and helium (He).

2. Periodic Table Structure

The periodic table is a structure of the chemical elements that describe their physical, electrical and magnetic characteristics. The table contains the number of protons (positively charged) and neutrons (negatively charged) in each element. For example, on the periodic table, this means that each element can be represented by one set of three numbers:
Hydrogen: 1
Neon: 17.3
Krypton: 18.2
Argon: 19.4
Ytterbium: 22.8
Beryllium: 24
Polonium: 29.6
Arsenic: 32
Iodine: 33

3. Properties of the Elements

The periodic table is a vital tool for scientists who need to quickly refer to basic information about an element. The periodic table also helps us to understand the relationships between and among the elements, and to identify certain elements as rarer than others.
The periodic table is organized into rows and columns, with each row representing an atomic number (A1, A2, etc.) and each column representing an atomic mass unit (atomic weight in grams).
Unlike the traditional view of the periodic table that places all of the elements in a single column, this arrangement has been created to break down the way that elements are grouped into families. The symbols used in the periodic table represent these families – e.g., hydrogen can be found throughout the rows as well as columns. While many of these family groups are based on elemental groups within groups (e.g., all atoms in group 1 are carbon), it is also possible for some elements to be found scattered throughout a family group (e.g., certain noble gases). Other elements have been placed in multiple columns or rows depending on their properties (e.g., boron occurs in different columns from those of nitrogen, but both are members of group 14).

4. Applications of the elements

The periodic table is used to quickly refer to information about an element, like atomic mass and chemical symbol. It’s also the inverse of a dictionary. The series is used to quickly identify what an element does in the universe, and how it relates to other elements in the universe. The periodic table is also used to describe why some elements exist while others don’t.

5. Conclusion

The periodic table is an organization chart for the elements of the periodic table. In the absence of an official name, or if one is not available, the element symbol is used as a placeholder.
The term “periodic” refers to a repeating pattern in which each element occupies a distinct position on the table.
In fact, there are several names and proper nouns used to refer to those elements that are grouped according to their positions on the table. For example, lithium is commonly referred to as #1 in the group of alkali metals (for its 1st place position), while beryllium is commonly referred to as #2 in that same group.
