This element is tellurium with a covalent atomic radius of 140 pm.
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.
Element Ununoctium has the largest atomic mass. The element with the largest atomic mass that has been named so far is Roentgenium.
The element of Antimony (Sb) would have the atomic weight of 121.75.
Sulfur is a non meta element. Atomic mass of it is 32.065.

nitrogen- .70 angstroms (oxygen- .66 angstroms)
A. Atomic Mass B. Atomic Number C. Atomic Radius D. Ionization energy
Atomic radius increases down the group. So larger atomic radius are present at the bottom.
Element Ununoctium has the largest atomic mass. The element with the largest atomic mass that has been named so far is Roentgenium.
Quantum mechanics do not give atoms a fixed size, since there are excited states which make electrons jump into a higher orbital and eventually might ionize the atom. However, the closest thing is "Element six times more atomic radius than chromium" which would be an element with 840 pm (10*10^-12 meters) that is not to be discovered quite yet, or so since osmium is only 840 kJ/mol in ionization energy. Make sure the units are the same.Osmium only has an empirical atomic radius of 185 pm, and chromium's empirical atomic radius is 160 pm.
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
The element with an atomic number of 113 is Ununtrium.
The element of Antimony (Sb) would have the atomic weight of 121.75.
Elements atomic radii increase in size as they run down the columns of the periodic table or across the periodic table from right to left. So, Al is larger than Cl. XP
Atomic radius decreases across a row (increasing positive charge in the nucleus causes electrons in the same energy level to "shrink" into the nucleus due to electrostatic attraction). This means that potassium has the largest atomic radius in period 4.
