The elements in a group do not have the same number of shells, however, the elements in a horizontal row do have the same number of shells.
shells
The table was organized so that elements of similar properties are in the same group. What (partly) determines reactivity is the number of electrons an atom has in it's ground state. . Within the atom electrons are organized in shells. Atoms are stable when they have 8 electrons in their outer shell (for hydrogen and helium it is 2 electrons.) . Elements of: Group 18 have 8 electrons in their outer shells Group 17 have 7 electrons in their outer shells Group 16 have 6 electrons in their outer shells Group 15 have 5 electrons in their outer shells Group 14 have 4 electrons in their outer shells Group 13 have 3 electrons in their outer shells Groups 3-12 have varied number of electrons in their outer shells Group 2 have 2 electrons in their outer shells Group 1 have 1 electron in their outer shells
Assuming that series is used the same way as group in the periodic table, elements in the same series have the same number of valence electrons.
It means that the elements have same number of shells. Period determines the number of shells of an element.
Elements in the same group have the same number of valence electrons, which determines their chemical properties. This leads to similarities in reactivity and chemical behavior among elements in the same group.
shells
A group of 17 elements is called a period in the periodic table. This period corresponds to the number of electron shells in an atom within that group. Elements in the same period have the same number of electron shells.
Atoms of the elements in a group have the same number of electrons in their outer energy shells. This gives the elements similar Chemical Propetries.
Elements in the same group have similar properties because they have the same number of valence electrons. In contrast, elements in the same period do not necessarily have similar properties, as their chemical behavior is determined by the number of electron shells they have.
They have the same number of electrons on their outer shells Hope this helped, if it does please recommend me it would be much appreciated

The groups on 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. The periodic period of elements refers to the horizontal rows on the periodic table, which indicate the number of electron shells an element has. Elements in the same period have the same number of electron shells, but elements in the same group can be in different periods.
Elements in the same period share the same number of electron shells, or energy levels. This means they have similar atomic sizes and exhibit similar chemical properties due to their outermost electron configuration.
Assuming that series is used the same way as group in the periodic table, elements in the same series have the same number of valence electrons.
Elements in the same group or family have similar chemical properties because they have the same number of electrons in their outermost energy level. This leads to similar reactivity and bonding behavior. Additionally, elements in the same group often have similar physical properties, such as melting and boiling points.
It means that the elements have same number of shells. Period determines the number of shells of an element.
