The atomic radius decrease from left to right.
Xenon is located in Group 18 of the periodic table, which is known as the noble gases. It is also found in Period 5. This places Xenon among the elements that have complete valence electron shells, contributing to its chemical inertness.
Two metalloids found in period 4 are silicon and germanium. These elements have properties intermediate between metals and nonmetals, making them useful in semiconductors and other electronic applications.
They change with atomic number.
In Period 3 of the periodic table, the least reactive metals are found towards the right side, specifically in the group of elements that includes aluminum (Al) and silicon (Si). Among these, aluminum is less reactive compared to sodium (Na) and magnesium (Mg), which are located on the left side of the period. However, metals in Period 3 are generally less reactive than alkali metals and alkaline earth metals found in earlier periods.
Hydrogen is placed in group-1 and period-1 in the periodic table as hydrogen has only one electron.
Some elements found in the same period as xenon (period 5) are barium, cerium, and iodine. These elements are all located in the fifth row of the periodic table, indicating that they have similar electron configurations and properties.
Elements with same properties are found in same group.They are also called families.
it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.

The period number is equal to the number of energy levels. Elements of period 3 have 3 energy levels. Na,Mg,Al,Si are few elements in the period 3.
They change with atomic number.
there are more electrons in the elements on the bottom of the table.
The elements found in Period 2 of the periodic table are lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
Elements with similar chemical properties are found in the same group on the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical behavior. Elements in the same period have different numbers of electron shells, leading to varying chemical properties.
Nitrogen can be found in the 1st period of group 15 elements in the periodic table.
