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 horizontal rows in a periodic table are called periods. Periods represent the number of energy levels an atom's electrons occupy in an element's electron cloud.
Rows in the periodic table are called periods. There are seven periods in the periodic table which represent the energy levels of the elements. Each period signifies the number of electron shells an element has.
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.
Periods are the horizontal rows on the Periodic Table. Cu is in the 4th row. Therefore, copper is in period 4 on the Periodic Table.
Periods are the horizontal rows on the Periodic Table. Cu is in the 4th row. Therefore, copper is in period 4 on the periodic table.
The horizontal rows in the periodic table are called periods, and the vertical columns are called groups or families. Periods indicate the number of electron shells an element has, while groups determine the number of valence electrons.
