Kr is a non-metal
Love, Grahamcracker
Krypton is the only non-metal in this list.
No, Pt is not a nonmetal. It is a transition metal located in group 10 of the periodic table. It is known for its durability, ductility, and high melting point.
PtCl2 is ionic. It consists of a metal (Pt) and a nonmetal (Cl), which form an ionic bond due to the transfer of electrons from Pt to Cl.
NO!!! Pt is platinum , which is a metal, found in the Transition Block of the Periodic Table.
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.

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.
PtCl2 is ionic. It consists of a metal (Pt) and a nonmetal (Cl), which form an ionic bond due to the transfer of electrons from Pt to Cl.
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.
Pt and an atomic number of 78
NO!!! Pt is platinum , which is a metal, found in the Transition Block of the Periodic Table.
The abbreviated electron configuration for Pt is [Xe] 6s1 4f14 5d9. also, the configuration for Pt2+ ion is [Xe] 4f14 5d8
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.
Although it is a mistakingly incorrect number (too low), it is commonly said to be elements in the periodic table
