7: one for each period.
The periods in the periodic table refer to the horizontal rows that indicate the number of electron shells an element's atoms have. There are 7 periods in the periodic table, each corresponding to the number of electron shells found in elements within that period.
The periodic table includes 7 periods, which are horizontal rows that represent the same number of electron shells in an atom's structure. Each period corresponds to the energy level of the electron shells within the elements in that row.

A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
Periods on the periodic table refer to the horizontal rows that categorize elements based on the number of electron shells they have. There are a total of 7 periods on the periodic table, each representing a different energy level for the elements within that row.
Periods have same shells. There are 7 periods in periodic table.
The periods in the periodic table refer to the horizontal rows that indicate the number of electron shells an element's atoms have. There are 7 periods in the periodic table, each corresponding to the number of electron shells found in elements within that period.
They are put into periods based on their number of electron shells.
Periods on the periodic table are the rows running horizontally from left to right. There are seven periods in total, each indicating the number of electron shells an element's atoms possess. As you move from the top to the bottom of a period, the electron shells increase by one.
The elements on the periodic table are separated into periods based on the number of electron shells they have. Elements in the same period have the same number of electron shells, which influences their chemical properties and reactivity.
They have the same number of electron shells.
There are 7 periods. These describe number of shells.
The period number is equal to the number of shells. Periods are the horizontal rows on the periodic table. The number of shells increases down a group.
The rows going across the periodic table are known as periods and contain elements with the same number of electron shells.
The periodic table includes 7 periods, which are horizontal rows that represent the same number of electron shells in an atom's structure. Each period corresponds to the energy level of the electron shells within the elements in that row.
Periods neither have same protons nor neutrons. They have same shells.
