Helium because helium is the lightest type of air in the period table of elements. Oxygen is next, because we breathe it and it helps life to live, but it can suffocate plants. Helium is made for balloons, and so much more.
Silver (Ag) #47 is on the periodic table of elements. A metallic element.
On the periodic table Ni represents the element Nickel.
The element following the 3rd periodic table element (lithium) is beryllium, which exhibits metallic character. Beryllium is a metal with properties such as high melting and boiling points, luster, and electrical conductivity.
Zi is not a recognized element on the periodic table. If you meant Zn, it stands for Zinc, which is a metallic element commonly used in a variety of industries, including galvanization and battery production.
