Lutetium
In a true periodic table, those two series would actually be inserted between Ba and Lu and between Ra and Lr. These elements have separate properties than others in the periodic table, and adding them directly in their place (instead of just separating them) would disrupt the classical group numbering system, make the periodic table ridiculously long, and just plain make it even harder to understand.
Atomic No. 8 is Oxygen , symbol 'O' (The 'O' is always written as a capital letter. However, when stating No. 8) do you mean Group 8(Also known as 16), which are the Noble/Inert gases. They being Helium(He) , Neon(Ne) , Argon(Ar), Krypton(Kr), Xenon(Xe), Radon(Ra). Please be no accurate with your request from the Periodic Table.

LU can stand for many different things. Some of them are Lehigh University, Longwood University, Lesley University, and Liberal Union, a party in the Netherlands. LU is also an acronym for Livestock Unit and London Underground.
Lutetium
Lu is for Lutetium on the periodic table.It has atomic number 71.It is a silvery white metal.
This element is lutetium (Lu).
Cs (Caesium) is the most reactive!!!!
there is no known element whose symbol is "Le" but there is: Li (lithium), Lr (Lawrencium), Lu (Lutetium), La (Lanthium)

Cesium, since barium and lutetium are also metals.

If you look up the elements in the periodic table by their atomic numbers, 7 = N, 18 = Ar, 49 = In. Narin. First name = ? 2 digit element 71=Lu,18=Ar,84=Po,49=In(also *4=Be)............jus clues
