What element has a half-life of only 8 seconds?
The answer is Radium
Element with shortest half life?
Technetium-97 has the shortest half-life of any naturally occurring element, with a half-life of about 4.2 million years. Artificially produced elements typically have even shorter half-lives, with some lasting only fractions of a second.
If Astatine-218 has a half-life of 1.6 s Suppose you have a 1.2-g sample of astatine-218 How much of the sample remains unchanged after 6.4 seconds Explain how you solved the problem?
After 1.6 seconds, 0.6 g astatine-218 remains unchanged. This amount is reduced by half to 0.3 g at 3.2 seconds. It is halved again at 4.8 seconds to 0.15 g, and halved once more to 0.075 g unchanged after a total of 6.4 seconds.
What is the normal phase of astatine?
That is in The Science in matter. It's normal phase is Halogen.
The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
Is astatine bad?
As a radioactive element with a short half life astatine is dangerous.
What is the Atomic mass of astatine?
The atomic mass of astatine is 209.9871 atomic mass units (amu). The atomic mass is given for the longest lived isotope of astatine, which is astatine-210, with a half life of 8.3 hours.
Describe about the stability of astatine?
All the isotopes of astatine are radioactive and unstable; the most stable isotope is 210At with a half life of 8,1 hours.
What element has a half-life of only 8 seconds?
The answer is Radium
Is astatine odorless?
Astatine is rarely encountered in nature, but when it does occur, it is typically in very small amounts and with a short half-life. Given its extremely limited presence and reactivity, there is insufficient information to definitively conclude whether astatine is odorless or not.
Where does Astatine go after its half-life?
It doesn't "go" anywhere. It radioactively decays and changes into a different element.
Is there an acid made with the element astatine?
Yes, astatine can form astatine hydride (HAt) which is an acid, although it is extremely rare and unstable due to astatine's radioactivity and short half-life. This compound has not been extensively studied due to the difficulties in working with astatine.
Why is astatine is the rarest element on the earth?
Astatine is the rarest naturally occuring element on Earth because all its isotopes are radioactive with very short half-lives. The most stable, At-210 has a half-life of 8 hours, so any astatine that forms (by radioactive decay of heavier elements) quickly decays to other elements.
What is the most radioactive of the halogen elements?
1. astatine is a halogen that is radioactive.
What is the eighty fifth element in the periodic table of the elements?
The 85th element in the periodic table is astatine (At). Astatine is a rare and radioactive element that belongs to the halogen group, similar to fluorine and chlorine. It is primarily produced synthetically in laboratories due to its short half-life.
What are the differences between astatine and bromine?
Astatine is a radioactive element, while bromine is a non-radioactive element. Astatine is a rare element with a very short half-life, while bromine is a common halogen with various industrial uses. Astatine is highly toxic due to its radioactivity, while bromine is toxic in its liquid and gas forms but not radioactive.
Element with shortest half life?
Technetium-97 has the shortest half-life of any naturally occurring element, with a half-life of about 4.2 million years. Artificially produced elements typically have even shorter half-lives, with some lasting only fractions of a second.
