You are watching: Based on the periodic table, what do we now call the element mendeleev called eka-manganese?
The Mbromheads.tvdeleev elembromheads.tvt called eka-manganese is now called Technetium.
Technetium is a crystalline, silver and radioactive metal, very similar to platinum. That serves as a gamma ray resource of beta particles. Many of the technetium created on planet is a byproduct of uranium-235 fission in atom reactors and is extract from nuclear fuel rods. No isotope the technetium has actually a half-life of an ext than 4.2 million years, so its detection in 1952 assisted reinforce the concept that stars can produce heavier elembromheads.tvts.

Which cabinet living organism space diploid
which cabinet living organism are diploid?
Ploidy is the area of biological that describes the number of chromosomes in a cell. Therefore, cells v two sets space diploid, and also those v one set are haploid. In diploid organisms, such together humans, the haploid cell are supplied only for the sex cells for reproduction, when the rest of the cells space diploid.

The half-life that radium-226 is 1590 years. If a sample has 100 mg, how numerous mg will continue to be after 1000 years?
In this case, we should remember the for the required time because that a radioactive nuclear species as radium-226 to decrease come one half its initial amount we room talking around its half-life. Furthermore, the amount of remaining radioactive product as a duty of the half-lives is computed together follows:
Therefore, because that an initial amount of 100 mg through a half-life of 1590 years, ~ 1000 years, we have:
