As you move down a group in the Periodic Table, elements have additional electron shells compared to those above them. This results in an increase in atomic size and a greater distance between the nucleus and the outermost electrons. Consequently, the outer electrons experience a greater shielding effect from the inner electrons, influencing their reactivity and other chemical properties.
The element in group V of the periodic table with 3 electron shells is Phosphorus (P). Group V elements have 5 valence electrons and the number of electron shells corresponds to the period number on the periodic table, so a Group V element with 3 electron shells is in period 3.
All noble gases or group 18 elements.
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.
All elements in group 16 share similar properties because their valence shells all contain the s2p4 electron configuration.
Any two of the alkali metals, group I of the periodic table: Li, Na, K, Rb, Cs and one extra: the only non metal in group I Hydrogen (H2).

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.
All these have one electron in their valence shell.
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.
The element in group V of the periodic table with 3 electron shells is Phosphorus (P). Group V elements have 5 valence electrons and the number of electron shells corresponds to the period number on the periodic table, so a Group V element with 3 electron shells is in period 3.
All noble gases or group 18 elements.
A Sodium atom has three shells. For future reference, this can be discovered later by looking at which period an element falls in. For example, all group 1 elements have 1 shell, all group 2 elements have two shells, and so on.
The number of shells in periodic table increase down the group, i.e., vertically.
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.
All elements in group 16 share similar properties because their valence shells all contain the s2p4 electron configuration.
All elements in group 16 share similar properties because their valence shells all contain the s2p4 electron configuration.
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.
