What else can I help you with?
What element has the symbol At?
The element with the symbol At is Astatine. Astatine is a Group 17(7) Halogen and is radioactive. It has 85 electrons in 6 shells, with 7 electrons in the outer shell.
What is the halogen in period 6?
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
Why is Astatine not a diatomic element?
Astatine is not a diatomic element because it is in a group of halogens that are typically diatomic in nature, but astatine atoms are too large and unstable to form stable diatomic molecules. Its reactivity and nuclear instability make it difficult to exist as a diatomic molecule.
What is the least active halogen?
Helium, the noble gas with the smallest atoms.
Is astatine flamable?
Astatine is not flammable because it is a halogen with poor reactivity and low flammability. It is a highly radioactive element and is very rare in nature.
What type of element is astatine?
Astatine is an element with the symbol At.
What the element is halogen?
Astatine, the always radioactive one.
What halogen is in period 6?
This chemical element is astatine (At).
What element has the symbol At?
The element with the symbol At is Astatine. Astatine is a Group 17(7) Halogen and is radioactive. It has 85 electrons in 6 shells, with 7 electrons in the outer shell.
What element has a electron of 85?
The element with the atomic number 85 is Astatine (At). Astatine is a Radioactive Halogen in Group 17(7) of the Periodic Table. Astatine has 85 electrons in 6 shells with 7 electrons in the outer shell. Astatine is the third radioactive element on the Periodic Table.
What element is most similar to astatine?
Iodine is the element most similar to astatine. Both elements are in the halogen group on the periodic table, sharing similar chemical properties due to their valence electron configuration. Astatine is a rare and highly radioactive element, making it difficult to study in detail.
What element is the rare halogen?
Astatine, the always radioactive one.
What is the halogen in period 6?
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
What is the formula for gaseous astatine?
At2(g) is the formula for gessoes astatine.
Why is Astatine not a diatomic element?
Astatine is not a diatomic element because it is in a group of halogens that are typically diatomic in nature, but astatine atoms are too large and unstable to form stable diatomic molecules. Its reactivity and nuclear instability make it difficult to exist as a diatomic molecule.
What halogen is located in the second period?
Iodine, element number 53 is the halogen (Group 17) element in period 5.
Which element has the largest radius in the halogen family?
As far as the Earth goes, fluorine is the most abundant halogen present in the Earth's crust. Chlorine, however, is the most abundant halogen in the universe.
