Is Platinum 190 stable?
Naturally occurring platinum (78Pt) consists of five stable isotopes (192Pt, 194Pt, 195Pt, 196Pt, 198Pt) and one very long-lived (half-life 6.50×1011 years) radioisotope (190Pt).
What does platinum radioactively decay into?
In alpha decay, the unstable isotope will emit an alpha particle, along with a more stable isotope (or isotopes). The masses of the elements are conserved during alpha decay. In this reaction, platinum-175 undergoes α-decay to produce osmium-171.

What is the half life of platinum?
50 years
Naturally occurring platinum is composed of five stable isotopes and one radioisotope, Pt-190, which has a very long half-life (over 6 billion years or 190 Ps). There are also many other radioisotopes with the most stable being Pt-193 with a half-life of 50 years.
Why is Platinum-190 so expensive?
I should note now that the elements francium, astatine, and californium are all radioactive. So even if you could produce enough stable material and could afford it, you wouldn’t want to own it. Platinum-190 is not radioactive. So, technically, platinum-190 is the most expensive metal you could possibly own safely.
Does platinum have any isotopes?
Natural platinum is a mixture of six isotopes: platinum-190 (0.012 percent), platinum-192 (0.782 percent), platinum-194 (32.86 percent), platinum-195 (33.78 percent), platinum-196 (25.21 percent), and platinum-198 (7.36 percent).
How much does Platinum-190 cost?
As of this writing, a well-known chemical supply firm now lists platinum-190 at a 4.19% enrichment for $4,890 per milligram with a delivery of 6-8 weeks. Mathematically this converts to $116,706,444 per gram in its pure state.
How many neutrons does Platinum-195 have?
117
Properties of Platinum-195 Isotope:
| Properties of Platinum-195 Isotope: | PLATINUM-195 |

What’s the rarest metal on Earth?
francium
The rarest stable metal is tantalum. The rarest metal on earth is actually francium, but because this unstable element has a half life of a mere 22 minutes, it has no practical use.
Is platinum more expensive than palladium?
Platinum has been the most expensive metal used in jewelry and therefore, has more status and brand caché. Over the last ten years, more and more couples were choosing palladium. For many, the choice came down to price. Palladium wedding bands typically ran about half the cost of platinum bands.
Does platinum oxidize?
Platinum is chemically inert and will not oxidize in air at any temperature. It is resistant to acids and is not attacked by any single mineral acid but dissolves readily in aqua regia. The metal is rapidly attacked by fused alkali oxides and by peroxides and will react with fluorine and, at red heat, with chlorine.
