The difference in atomic number between adjacent elements is always one (1).
Gaseous elements are typically found on the right side of the periodic table, in the nonmetals group.
Chlorine is located in Group 17 (halogens) on the Periodic Table of Elements. It has the atomic number 17 and symbol Cl.
The periodic table generally contains more metallic elements than nonmetallic elements. Metals are found on the left side of the periodic table and make up the majority of elements, while nonmetals are mostly located on the right side. However, there are exceptions, such as the metalloids group that have properties of both metals and nonmetals.
Beryllium, sodium, calcium are its neighbours.
Gallium is in group 13 of the periodic table. The other elements in this group are Boron, Aluminum, Indium, and Thallium.
In the columns of the periodic table, chemical properties are similar.
Their atomic number differ by 1. It is applicable for elements located next to one another.
The difference in atomic number between adjacent elements is always one (1).
Stable Elements in the periodic table are located in Group 18 of the periodic table.It is a group of noble gases.Noble gases are considered most stable in nature.
Metals are located on left side in periodic table.Eg-group 1,2 elements
Representive elements
On the left of the periodic table, especially group 1 and group 2 elements.
Elements with full outer shells, the noble gas elements, are located in the column at the extreme right of the periodic table.
Nonmetals.
Alkali metals are group-1 elements. They are located at extreme left in periodic table.
Gaseous elements are typically found on the right side of the periodic table, in the nonmetals group.
