A period is a horizontal row on the Periodic Table of the elements. There are seven periods on the periodic table. Each period corresponds to the highest energy level that contains electrons. For example, the elements in the first period have electrons in the first energy level, which is the only energy level available; the elements in the second period have their highest energy electrons in the second energy level; the elements in the third period have their highest energy electrons in the third energy level, and so on.
A period in the periodic table of the elements are simply arranged in order of increasing atomic number. The atomic number or proton number is usually shown above the symbol for the element.
A period is a row on the periodic table. There are 7 periods total.
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.

In chemistry, none! the period table does not exist one can only find the periodic table although the rows of the periodic table are called periods or series. !
1st period,2nd period ,3rd and 4th period
A row of elements is known as a "period".
It depends on your individual body chemistry.

Chemistry is entirely dependent on chemistry. If it weren't for chemistry, chemistry wouldn't exist.
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.

language is different, filipino chemistry is chemistry of filipine, foreign chemistry is chemistry of that country
Chemistry is the chemistry if youre a chemistry then good for you
