Groups are arranged as columns in the periodic table; the contained elements have similar properties.
Periodic table is arranged by atomic number. elements are arranged in groups and periods.
Periodic table is arranged in rows and columns. there are 7 periods and 18 groups.
Periodic table comprises of elements. These are arranged in groups and periods.
The periodic table has 7 periods and 18 groups. The order of elements is governed by the number of protons.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.

Periodic table is arranged in rows and columns. there are 7 periods and 18 groups.
Periodic table comprises of elements. These are arranged in groups and periods.
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
The periodic table of Mendeleev contain now 118 chemical elements arranged in groups and periods.
The elements are arranged in order of increasing atomic number in the Periodic Table. The rows are called periods and the columns are called groups.
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
The periodic table has 7 periods and 18 groups. The order of elements is governed by the number of protons.
In the periodic table, the elements are arranged by atomic number
Periodic table was initially arranged by Mendeleev. It was rearranged by Moseley.
