The abbreviated electron configuration for Pt is [Xe] 6s1 4f14 5d9. also, the configuration for Pt2+ ion is [Xe] 4f14 5d8
Xe
Xenon (Xe) does not have to follow the octet rule because of its access to the 4d sublevel. Xe is placed in the center and single bonded to two fluorine atoms that are 180 degrees apart. There are 3 lone pairs on the Xe atom.
These are the noble gases, He, Ne, Ar, Kr, Xe, Rn

Some examples of elements is iron(Fe), Hydrogen (H) and Sulfur(S).Elements presents in periodic table like hydrogen , helium , lithium , beryllium , boron ,carbon , nitrogen , oxygen etc called elementsAn element is a substance that can not be broken down into any other chemically distinct substance. Examples would be sulfur, oxygen, nitrogen, gold, and lead.
These are the noble gases: He, Ne, Ar, Kr, Xe, Rn.
