39. Yttrium and 70. Ytterbium
In the Periodic Table of Elements there are: 118 Observed Elements 114 Officially Discovered Elements 112 Officially named Elements 92 Naturally Occuring Elements 83 Non-radioactive elements
Beryllium, sodium, calcium are its neighbours.
Stainless steel is not found on the periodic table. It is a metal alloy made from a combination of iron, carbon, and other elements such as chromium and nickel. These elements are found on the periodic table.
CO2 is not on the periodic table. The periodic table of elements, funnily enough houses all the elements. CO2 is a compound made up of other elements and therefore isnt on the table.
Well, Back when Medeleev made this table, many of the elements were not even discovered yet. He plotted only the elements that he knew on his table. He organized them by increasing atomic weight. He didn't know all the elements so he would put question marks and empty spaces in the spots he thought elements would be and left to be found by other scientist. He happened to be true about the missing elements and that scientist did end up finding these "missing links" of the periodic table and led to the new or modern periodic table. The modern periodic table doesnt have any missing elements and they changed Medeleev's way of organizing the table by increasing atomic weight to increasing atomic number. So the newer form of the periodic table was complete and made it easier to find what elements react better with other elements. This making the modern table became the more efficent table of our time.
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
The two elements in periodic table which are liquid are: 1 mercury 2 bromine
Water is a COMPOUND of two(2) elements, viz. Hydrogen(H) and Oxygen(O). These tqo elements are both found in the Periodic Table. The Periodic Table is a list of ELEMENTS, not compounds.
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).
The periodic table lists element and not minerals.
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
It isn't on the periodic table since it is not a single element but a compound made of two elements: hydrogen and chlorine.
The two periods below the periodic table are known as the lanthanides and actinides. These series consist of elements that fall within the f-block of the periodic table.

I can find only two types The Mendeleves Periodic table based on Atomic weight of elements and The Modern Periodic table based on Atomic number of elements.
The f-block elements (lanthanides and actinides, the two rows at the bottom of the periodic table) are known as inner transition elements
Naturally occurring and man made elements
