The element with atomic number 85 is astatine, symbol At
The atomic number is the number of protons, so the atomic number of astatine is 85.
At stands for astatine which is in group 7 of the periodic table.
It is relatively rare, you will not usually see it on a daily basis.
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.

Astatine atomic number 85 is also known as "astatine" - it is a highly radioactive element in the halogen group found on the periodic table.
Rubidium is a metal element. Atomic mass of it is 85.
The halogens are a group of elements in the periodic table that includes fluorine, chlorine, bromine, iodine, and astatine. They are located in Group 17, and their atomic numbers increase across the period from fluorine (atomic number 9) to astatine (atomic number 85). This means that each halogen element in this group has one more proton in its nucleus compared to the previous element, resulting in an increase in atomic number.
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.
