Which element in the halogen group has 30 grams of this element in the earth's crust at any one time?
The halogen group includes fluorine, chlorine, bromine, iodine, and astatine. Among these, bromine is estimated to have about 30 grams available in the Earth's crust at any one time. This is due to its relatively low abundance compared to the other halogens, particularly fluorine and chlorine, which are more prevalent in nature.
How many grams of francium exist in the earth's crust at any one time?
It is estimated that there are around 340 grams of francium in the Earth's crust at any given time. Francium is a highly unstable and rare element, with a half-life of only about 22 minutes, making it very hard to find in nature.
Which layer of earth's interior is the thinnest and what is the density of that layer?
The thinnest layer of Earth's interior is the crust, which varies in thickness from about 5 to 70 kilometers. The average density of the continental crust is approximately 2.7 grams per cubic centimeter, while the oceanic crust has a higher density of about 3.0 grams per cubic centimeter. The crust sits atop the mantle, which is much thicker and denser.
Where is promethium found in the world?
You don't. It's made in a cyclotron or reactor. It has no stable isotopes.There are trace quantities in some radioactive ores, where it occurs as a decay product of other elements (for example, in pitchblende as a result of a the spontaneous fission of uranium).The largest scale production of promethium ever on Earth was at Oak Ridge National Laboratory, where they could produce about 650 grams of it per year. That's a bit under a pound and a half.
If there is a concentration of 4 grams per metric ton of uranium in the Earth's crust then what mass of uranium is found in 1.3 milligrams of the Earth's crust?
To calculate the mass of uranium in 1.3 milligrams of the Earth's crust, you can use the concentration provided. First, convert the concentration into milligrams (1 metric ton = 1,000,000 milligrams), which gives 4 mg per 1,000,000 mg. Then, use this ratio to find the mass of uranium in 1.3 mg by setting up a proportion: (4 mg / 1,000,000 mg) = (x mg / 1.3 mg). Solving for x gives approximately 0.0000052 grams of uranium in 1.3 milligrams of the Earth's crust.
What element has no more than 30 grams in the Earth's crust at any one time?
30 grams of Astatine can be found in the earths crust at any one time.
What element has no more the 30 grams in Earth's crust at any one time?
30 grams of Astatine can be found in the earths crust at any one time.
How much francium is there is the world?
Francium is probably the rarest element found in the Earth's crust. As Francium is so rare and the isotopes are so short-lived, we don't know too much about the element. So experts think that there is no more than 15 grams in the Earth's crust. I hope I answered your question right
What is the rarest element on earth?
The rarest naturally occurring element on Earth is astatine. It is a radioactive element with a very short half-life, making it extremely rare and difficult to study. It is estimated that there is only a few grams of astatine present in the Earth's crust at any given time.
What is the abundant in the earth's crust for xenon?
Xenon is a trace element in Earth's crust, with an abundance of about 0.000009 grams per kilogram of crustal rock. It is found in trace amounts in minerals such as xenon ores, and is most commonly extracted from the atmosphere.
How many grams of oxygen in the Earth's crust?
Oxygen makes up about 46.6% of the Earth's crust by weight. The approximate total mass of the Earth's crust is around 2.7 x 10^22 grams. Therefore, you can calculate the grams of oxygen in the Earth's crust by multiplying these two percentages.
Which element in the halogen group has 30 grams of this element in the earth's crust at any one time?
The halogen group includes fluorine, chlorine, bromine, iodine, and astatine. Among these, bromine is estimated to have about 30 grams available in the Earth's crust at any one time. This is due to its relatively low abundance compared to the other halogens, particularly fluorine and chlorine, which are more prevalent in nature.
The density of Earth's crust is what?
The average density of the Earth's crust is 2.7 grams per cubic centimeter.
Name the element found in small amounts?
The rarest naturally occurring element is astatine (At), with an estimate of only 25 grams in the earths crust. The rarest man-made element is francium, which has a half life of only 20 minutes, and must be constantly produced in order to be studied.
If 32 grams of an element was equal to 1 mole of the element what is that element?
There are 32 grams of sulfur in a mole of that element. There are also 32 grams of oxygen in one mole of oxygen as it is found in its natural state (O2).
Is francium in earth?
Yes. Earth's crust is estimated to contain about 30 grams of Francium at any given time.
What element in group 7 is so rare that there is only a few grams of it on earth?
Astatine (At) is the element in group 7 that is so rare that there are only a few grams of it on Earth. It is a radioactive element and is created through the decay of heavier elements.
