A row on the periodic table is a horizontal arrangement of elements that share similar properties. These elements have the same number of electron shells. Each row represents one energy level or electron shell in an atom.
The Horizontal Rows are named 'PERIODS'. The Vertical Columns are named 'GROUPS'.
In chemistry, a row refers to a horizontal line of elements on the periodic table that have similar chemical properties. Each row represents a period in the periodic table and elements in the same row have the same number of electron shells.
A period on the periodic table refers to a row of elements that are arranged in order of increasing atomic number. Each period starts a new row and represents the number of electron shells an element has.
The horizontal rows of the periodic table are called Periods and the vertical rows are called groups.
