Astatine, with a molecular weight of 210 amu.
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.
Astatine, At. The halogens are in Group 17 (VIIA).
astatine
iodine
This element is barium.
Boron has the largest empirical atomic radius: 85 pm.
Element Ununoctium has the largest atomic mass. The element with the largest atomic mass that has been named so far is Roentgenium.
there isn't an eighth row in the periodic table of elements. The two rows at the bottom that aren't connected are actually part of the sixth and seventh row. However, in a row, the last one on the far right would normally have the larger atomic radius.
Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
francium has the largest ionic radius
The ionic radius of the iodide ion, I- is 206pm. It is one of the largest monatomic anions. The ionic radii of the halogen ions increase down the halogen group.
Francium has the largest atomic radius of all the elements on the Periodic Table.
Iodine element is a halogen. Iodine has the atomic number 53.
This element is barium.
Bismuth Francium has the largest atom - the greatest atomic radius.
Francium has the most larger atomic weight and also the largest atomic radius between the alkali metals.
Bismuth Francium has the largest atom - the greatest atomic radius.
Ununtrium (Uut)
Cesium
Bromine is farther down the group and has more electron shells, making it an element with a lager atomic radius.
Boron has the largest empirical atomic radius: 85 pm.
