Same reason only one O, N, Cl, etc. are written. These are all diatomic molecules, but as far as the ELEMENT goes, they are monoatomic.
No. Hydrogen peroxide is a compound. Only elements are listed on the periodic table.
hydrogen has no family on the periodic table.. its a loner
Hydrogen is in the periodic table because it is an element, and all elements are in the periodic table.
H stands for the element hydrogen. H2 is hydrogen molecule and is not listed on the periodic table.
Hydrogen has only 1 electron and hence it is placed at the top in the periodic table.
Hydrogen can be considered as a non metal. It is placed to the left of the periodic table.
You will not find H2S on the periodic table. The periodic table contains only elements, and H2S is a compound, made of two elements, hydrogen (H) and sulfur (S).
No, most nonmetals are on the RIGHT upper corner of the periodic table. The only nonmetal on the left side is hydrogen.
Hydrogen
The periodic table is only for elements while Ammonium is a compound radical or ion NH4+ it is combination of two elements nitrogen and hydrogen these two are in periodic table.
the nonmetals are located in the right of the periodic table and only one (hydrogen) is located in group 1, period 1
No, the periodic table only lists elements. Sulfuric acid (H2SO4) is a compound of three elements: hydrogen, sulfur, and oxygen.
