Kr is a non-metal
Love, Grahamcracker
Kr is not a metal. It is a noble gas.
Kr(Krypton) is a noble gas ; [non-metal] Pt (Platinum) is a metal Sc (Scandium) is a metal V(Vanadium) is a metal.
No, Platinum is a transition metal.
the substances on the table of elements that crisps are comprised of are: lithium Li europium Eu neon Ne platinum Pt phosphorus P francium Fr and finaly terbium Tb in the formula= LiEu2Ne5PtP2Fr10Tb3
Platinum (Pt) is a metal and not a non metal. You can verify this by using the Periodic Table of Elements.
The abbreviated electron configuration for Pt is [Xe] 6s1 4f14 5d9. also, the configuration for Pt2+ ion is [Xe] 4f14 5d8
It is Pt = platinum.
Kr(Krypton) is a noble gas ; [non-metal] Pt (Platinum) is a metal Sc (Scandium) is a metal V(Vanadium) is a metal.
No, Platinum is a transition metal.
Elements that are extremely unreactive include: Platinum (Pt), Gold (Au), Helium (He), Argon (Ar), Xenon (Xe), Krypton (Kr). These are unreactive because: Platinum and Gold are the bottom two elements in the metals Reactivity series. The rest are inert gases which are all unreactive.

Elements in the same family of the periodic table have the same number of valence electrons. For light elements this amounts to the same electron configuration, but for heavier elements this is not necessarily the case, e.g. Ni: [Ar]4d8 5s2 ; Pd: [Kr] 5d10 ; Pt: [Xe] 6d9 7s1 .However the whole underlying reason for the periodic law involves the number of valence electrons, and this is expressed in the periodic table.
There are 7 elements in group I of the PT. From Hydrogen(1) to Francium(87)
Pt and an atomic number of 78
its not a group but its called a compound. When two elements are combined it becomes a compound. Answer: Group 18, the noble or inert gasses, won't readily react/combine with other elements or if so with great difficulty. -Blue

One: Platinum. Atomic symbol Pt, with an atomic weight of 78 according to the periodic table.
