It is the interval between chemical elements, measured by the number of protons in its nucleus, at which many of the chemical properties are similar.

Chemistry
The periodic table of elements is not a real table with every element that exists but a chart with initials and these initials stand for the elements. For instance Al stands for aluminum and Na stands for sodium. Go figure right? :)
Inorganic chemistry is a branch of chemistry that focuses on the properties and behavior of inorganic compounds, while general chemistry covers all basic principles and concepts of chemistry, including inorganic chemistry. General chemistry is a broader discipline that encompasses various branches of chemistry, including inorganic chemistry.
Analytical Chemistry is the study of composition of matter. It is the branch of chemistry that deals with properties of materials and analysis of them with the help of tools.
1st period,2nd period ,3rd and 4th period
A row of elements is known as a "period".
It depends on your individual body chemistry.

In chemistry, a period is a horizontal row in the periodic table that represents the number of electron shells an atom has. Each period corresponds to the energy levels of an atom's electrons. The organization of elements in the periodic table is based on their atomic number and electron configuration, with elements in the same period having similar properties due to their electron arrangement.
there are five branches: inorganic, organic, analytical, physical, and biochemistry. they could be further broken down into sub-branches such as organometallic chemistry, physical organic chemistry, electroanalytical chemistry, and so on and so forth.
Chemistry
chemistry is very important. chemistry is different from bio chemistry .
Discovery of the 4 basic elements fire, water, earth and wind - Miro
there are many branches of chemistry. Organic chemistry is the study of chemistry of life. Inorganic chemistry is the study of inorganic compounds. Analytical chemistry is the study of the chemistry of matter. Physical chemistry is the study of chemistry applying physics. Biochemistry Radiochemistry Photochemistry Cosmochemistry Hydrochemistry Electrochemistry Clinical chemistry Neurochemistry Forensic chemistry Macromolecular chemistry etc.
