Smallest atomic radii
Webb28 mars 2024 · In period 2 from left to right, state which element has the largest atomic size and which element has the smallest, giving reasons. Answer: Factors affecting the atomic size are: Number of shells: As number of shells increases, atomic size i.e. the distance of the outermost shell from the nucleus also increases. WebbNoble gases have the smallest atomic radius of all HELIUM. This is due to the fact that nuclear radii decrease down a period and increase in a group, which is why Noble gases are the final group and HELIUM, being the top element, has the greatest atomic radius among noble gases.

Therefore, they can get the noble gas configuration either by gaining one electron to form uni negative ion, X-, or by sharing electrons with other atoms. Thus, they show an oxidation of state of -1 or +1. Do halogens have ionic radii?
