A General Explanation about Periodic Table

When you learn the exact sciences, especially in the fields of science such as physics and chemistry as well as engineering sciences and the application of science of course, you will be faced with the problem of how everything around us is formed, nothing is causing it all to form. However, my point here does not mean taking the principle of causality that leads to God the creator, but rather speaks to the flow of natural phenomena. 

Once upon a time, people saw the phenomena of nature occurring is a natural power that can not be followed. However, the development of science and technology has been growing rapidly teaches us how all the good things that are objects or events that are providing a scientific perspective to analysis and identify it. In 1869, when a chemical scientist from Russia published a journal about the elements is the reason why the world was created. Dmitri Mendeleev which is a chemical scientist who publishes word form Periodic Table of Elements is the reference for every student in the world to create new technologies that can solve every human problem on earth. 

Periodic Table of Elements is a method of classifying the elements that exist in this world, especially in the planet that describes the characteristics or attributes of the elements complete with electron configuration, atomic radius, atomic number indicates the number of protons and electrons, nature of the radioactivity of an element, electronegativity and others. This method helps students, especially among students and scientists in developing the technologies of the past, present and future.

In this method the elements of the periodic system there are rules about the period and group of the periodic system of elements due to the systematic preparation in a table. The system has the form:

Group. Often called a group or family in the periodic table of elements is a vertical column of elements in the periodic table. Naming class system is often used in teaching the properties of elements such as the number of outer electrons of each element. Here are some commonly used naming groups of scientists in classifying these elements:

• alkali metal
• Alkaline earth metal
• Boron Group
• Carbon Group
• Nitrogen Group
• Oxygen Group
• Halogen Group
• Noble Gas Group
• Transition Metal

Period. It is an arrangement of elements in the periodic system of elements vertically from left to right stating atomic radii and electronegativity properties and stability elements. Arrangement is called the period commonly used is the first period, the second, third as well lanthanides and actinida period.
