it provides the number of rings the element's atom has
The row number describes the period. It signifies the number of shells.
Carbon is in period 2. To find the period number, you can look at the row in which the element is located on the periodic table. Carbon is in the second row of the periodic table, so it is in period 2.
helium is in row 1 (or better period 1)
Chromium (symbol: Cr; atomic number: 24) is in the fourth period, or row, of the periodic table.
