Based top top the periodic table, the elembromheads.tvt mbromheads.tvdeleev referred to as eka-manganese is now referred to as technetium. Technetium is a silvery-gray steel that tarnishes slowly in moist air. Hope this answers the question. Have a nice day. Feel cost-free to ask much more questions.

You are watching: Based on the periodic table, what do we now call the element mendeleev called eka-manganese?



Answer:

Technetium

Explanation:

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.

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?
Katbromheads.tvnochek1 <597>

Answer:

*

Explanation:

Hello,

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:

*

Best regards.
