Atomic size increases down a group as the energy level (or shell) increases. So Astatine will have the largest size (radius) in group 17
From group 17 (7A), fluorine has the lowest atomic radius.
Ionic bond.
This element is chlorine (group 17).
Group 17, the halogens.
It is a difference between the empirical and the calculated atomic radius of an element; also all the values are only approximates. The empirical atomic radius of sulphur, phosphorous and chlorine is 100 pm. The calculated atomic radius of phosphorous is 98 pm.
From group 17 (7A), fluorine has the lowest atomic radius.
element 17 (Cl) chlorine belongs to the hologen group. It is a gas.
Ionic bond.
This element is chlorine (group 17).
Group 17, the halogens.
Astatine, with a molecular weight of 210 amu.
It is a difference between the empirical and the calculated atomic radius of an element; also all the values are only approximates. The empirical atomic radius of sulphur, phosphorous and chlorine is 100 pm. The calculated atomic radius of phosphorous is 98 pm.
Two of them. A group 2 element has two valency electrons whereas those in group 17 have 7. The latter need one electron to make an ionic bond so two of them can react with a single group 2 element.
{4/5, 41/50, 17/20, 75%} The Element Largest Value Is?
It is in group 17.
Chlorine belongs to group 17 of period 3.It belongs to Halogens group with atomic number 17.
Chlorine is a halogen, a group that includes fluorine, chlorine, bromine, iodine, and the rare radioactive element astatine. (And possibly the newly isolated element ununseptium.)
