Is cobalt unstable stable

Answer 1

Answer

iron is a metal and so is generally chemically stable but can react with water and switch with hydrogen (review activity series of chemical reactions) to create iron oxide (rust).

iron nuclei are very stable. Because of this, the iron content of the earth and the other planets will continue to increase over time. All nuclei are radioactive over a long enough timeline, as all nuclei have a chance of breaking down at any time. Iron is among the least radioactive of the elements.

Answer

There are four naturally occurring isotopes of iron, 54Fe, which is radioactive and accounts for 5.8% of naturally occurring iron, and 56Fe, 57Fe, and 58Fe.

In addition, there are 27 synthetic radioactive isotopes of iron, three of which have alternate isomers.

Answer 2

A:Yes and No. There is one isotope of (59Co) Cobalt that is stable but amongst there is another (58Co) that has a half life of 70 days. A:No. Cobalt ordinarily found in nature is not radioactive. Radioactive cobalt can be found as a result of human activity, but it is ordinarily only in trace quantities. Like all elements, synthetic radioactive isotopes of cobalt can be found.

Answer 3

Cobalt is not radioactive as in natural state. Isotope are inducted to produce radioactive Cobalt-60 which is used to treat patients.

Answer 4

Yes, cobalt is safe when using it as a medal. When you use it as a salt is is dangerous.

Answer 5

Uranium is radioactive and unstable.

Answer 6

Reactive
