Final answer:
Elements on the right side of the periodic table tend to form ions by gaining electrons and have different properties compared to the elements on the left side.
Step-by-step explanation:
The elements on the right side of the periodic table, in general, tend to form ions by gaining electrons. These elements are called nonmetals and have characteristics that differ from the elements on the left side, which are mostly metals. Nonmetals are poor conductors of heat and electricity, have lower densities compared to metals, and can exist in various states at room temperature including gases like oxygen, solids like sulfur, or liquids like bromine.
