The Periods are the horizontal rows on the periodic table.
Horizontal rows are called periods. There are 7 periods in periodic table.
The rows of elements in the periodic table are called periods. There are a total of 7 periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are arranged.
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.
Horizontal rows of elements in the periodic table are called periods. Each period represents a different energy level, with elements in the same period having the same number of electron shells. Periods are arranged in numerical order from left to right on the periodic table.
A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
In the periodic table chemical elements are orderd in periods and groups.
Horizontal rows are called periods. There are 7 periods in periodic table.
Horizontal rows are called periods. There are 7 periods in periodic table.
each row in the Periodic Table is called a period.
There are 18 periods in the periodic table. The periods are divided according to the chemical properties of elements. Elements in a group have similar properties.
The rows of elements in the periodic table are called periods. There are a total of 7 periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are arranged.

Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
The horizontal rows are periods on periodic table. There are 7 horizontal rows in modern periodic table.
The periodic table of Mendeleev contain now 118 chemical elements arranged in groups and periods.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
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.
