Why is radium still on Earth?
Radium is a decay product of uranium and is constantly being produced. U-238 has a half-life of about 4.5 billion years, so there's still quite a bit left of the original amount on Earth.
Who Radium is a member of the alkaline earth family. In addition to being a part of this family what is another property of radium that you can deduce from the information given in the periodic table?
Since Radium is in the alkaline earth metal group, and we know that as you move down the group, it gets more reactive. So, since Radium is the last element of the group, another property of Radium is that it is highly reactive in nature.
Are all half-lives the same between different element?
No. Some only last a tiny fraction of a second, some last hundreds of thousands of years.
What element does radium become once it has decayed?
Radium undergoes radioactive decay, specifically alpha decay, to become radon. Radium-226 (226Ra) will undergo alpha decay releasing that alpha particle, which is a helium-4 nucleus, to become radon-222 (222Rn).
What is the heaviest element of group 2?
It is about Cf element. it is in the !8th group.

What is the last of the alkaline earth metals?
Radium
If radioactive radium has a half life of approximately 1599 years What percent of a given amount remains after 980 years?
Luckily got it on my last try it was apparently 65.39%

How many minutes is physical activity?
Physical activity is not time-dependent. It can last for the tiniest fraction of a second or for years.
Are all half-lives the same between different element?
No. Some only last a tiny fraction of a second, some last hundreds of thousands of years.
Alphabatically which is the first and last of the Alkaline Earth Metals?
Barium Beryllium Calcium Magnesium Radium Strontium

Occupies the last place in the zero group of gases?
The element radium occupies the last place in the zero group of gases. The symbol for radium is Ra, and its atomic number is 88.
What is the heaviest element of group 2?
It is about Cf element. it is in the !8th group.
What fraction is closest to 1?
There is none. There will always be a fraction closer to 1 then the last.
What is bench mark fraction?
A bench mark fraction is a fraction that its denominator can be turned into 10 or 100, can simplify and i forgot the last reason. Hope this helps! :)
