These are the periods 4 and 5.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
Rows in the Periodic Table are called Periods.There are 7 periods in total.All the elements in period have same number of energy levels.
atomic number Chemical elements are organized in the form of the periodic table of Mendeleev, in groups and periods.
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.
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 are rows that categorize elements based on the number of electron shells they have. There are seven periods in total, each representing a different energy level. Elements in the same period have similar properties due to their electron configurations.
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.
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.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
