When looking at potassium and bromine, it would seem that with more electrons occupying more orbitals, bromine would be larger. However, in addition to those additional electrons, bromine also has additional protons. These protons in the nucleus pull on all of bromine's electrons with more strength than the nucleus of potassium, and the stronger pull offsets any size gained by adding electrons.
In short, bromine's nucleus pulls harder.
Bromine's atomic radii is larger than that of chlorine.
Both bromine an arsenic have the same atomic radius. :)
Bromine has a SMALLER atomic radius because it has one more electron shell than Iodine. On the periodic table, atomic radius of an atom decreases across a period and increases down a group. Since Bromine and Iodine are in the same group, you know Bromine has a smaller atomic radius because it is in a lower period.
Bromine is farther down the group and has more electron shells, making it an element with a lager atomic radius.
Caesium atom has a larger atomic radius.
bromine
Bromine
K (potassium) has the larger atomic radius.
Bromine's atomic radii is larger than that of chlorine.
barium silly
Bromine has a larger radius (not raduis) than chlorine.
The atomic radius of bromine is bigger.
Bromine's atomic radii is larger than that of chlorine.
Yes.
The atomic radius decreases across a period from left to right and increases down in a given group. That means that since the lower the element is in a group, the larger the atomic radius will be. The atoms with the largest atomic radii are located in Group I and are at the bottom of groups.
The atomic radius of bromine is lower.
Element 19, potassium: atomic radius = 227 pm. Element 35, bromine: atomic radius = 120 pm.
