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.

Helium is in the first period of the periodic table.
No. Xenon is not the first period of the periodic table. It is placed in the 5th period of periodic table.
No , Iodine is placed in period-5 of the periodic table.
Nickel is a natural element and technetium is an artificial element.For example technetium is placed in the group 7 and period 5 of the periodic table and nickel is placed in the group 10 and period 4 of the table.
Silver is in the period 5 and group 11 of the periodic table.
The difference between a period and a group is that:A periodic is a horizontal row of elements in the periodic table, which simply means the column of the periodic table.A group is a vertical row of elements in the periodic table, which simply means the row of the periodic table.
In the periodic table, a period is a horizontal row that represents the number of electron shells in an atom, while a group is a vertical column that shows the number of valence electrons in an atom.
Copper is located in period 4 of the periodic table.

Sulfur (S, element number 16) is on the third period of the periodic table.
A period on the periodic table is a row.This is the horizontal section of the periodic table.
Nickel is a natural element and technetium is an artificial element.For example technetium is placed in the group 7 and period 5 of the periodic table and nickel is placed in the group 10 and period 4 of the table.
