The element in the Periodic Table that has 85 protons is Astatine. This element is in the Halogen Family (Group 17 in the Table). This group includes the elements Fluorine, Chlorine, Bromine, and Iodine.
At-Astatine Because it is the 85th element of the periodic table. That means that it has 85 protons and 85 electrons
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.
The chemical element with atomic number 85 is astatine. It is a rare and highly radioactive element that occurs naturally in trace amounts. Astatine is part of the halogen group on the periodic table.
Protons/Electrons: 85 Number of Neutrons: 125
At stands for astatine which is in group 7 of the periodic table.
At-Astatine Because it is the 85th element of the periodic table. That means that it has 85 protons and 85 electrons

The element with atomic number 85 in the Periodic Table is Astatine (At). Astatine is the second radioactive element, but is not synthesised. It is part of the Group 17 - Halogens family. It has 85 electrons in 6 shells with 7 electrons in the outer shell.
At stands for astatine which is in group 7 of the periodic table.
That would be iodine with an atomic number of 53. The next group 17 element is astatine with atomic number 85.
At and it is number 85 on the periodic table!!
Radon (86). And all the halogens are "non metals".
The atomic number is the number of protons, so the atomic number of astatine is 85.
The atomic number of astatine (At) is 85.The atomic weight of At is 210 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
Astatine atomic number 85 is also known as "astatine" - it is a highly radioactive element in the halogen group found on the periodic table.
