Because K + has the biggest nuclear fee (Z = 19), that is radius is smallest, and also S 2− with Z = 16 has actually the biggest radius.

You are watching: Which of the following ions has the smallest radius?

## Which of the adhering to ions has the the smallest radius?

Explanation: The ion that has actually the the smallest atomic radius is . This is since fluoride is the most electronegative element, which way that electrons are more attracted to the nucleus.

## Which ion has actually the largest ionic radius?

Explanation: The ionic radii the cations follow the very same trends as atomic radii. They increase from top to bottom and also from best to left in the routine Table. Thus, the ion through the biggest radius is closest to the lower left corner of the periodic Table, and that is the K+ ion.

When an atom loses an electron to form a cation, the shed electron no longer contributes to shielding the various other electrons native the charge of the nucleus; consequently, the other electrons are more strongly attractive to the nucleus, and the radius the the atom it s okay smaller.

## Why is Fe2+ bigger 보다 Fe3+?

Fe2+ will certainly be larger than Fe3+. This is since the outermost electron in the Fe2+ ion is pulled off to kind Fe3+ ion. Together the electrons space removed, the reduces the repulsion increasing nuclear charge experienced by every of the other d electrons and decreases the dimension of the ion.

## Do girlfriend predict that the ionic radius the Sr2+ is bigger or smaller sized in size than the ionic radius of Mg2+?

Hence, native the electronic configuration that Mg2+ ( ) and also that the Sr2+ (), the Sr^2+ ion is much larger and has many much more intervening shells than Mg2+. Therefore it complies with that together we relocate down group 2, we mean that the ionic radius should increase in accordance through the reason provided above.

## Which is the the smallest radius?

Atomic radii vary in a predictable method across the routine table. As deserve to be watched in the numbers below, the atom radius rises from top to bottom in a group, and also decreases from left to right across a period. Thus, helium is the the smallest element, and also francium is the largest.

Hence, Cl has actually the smallest radius.

## Which particle has actually the the smallest radius?

Which element has the smallest atomic radius? Explanation: Helium has actually the the smallest atomic radius. This is because of trends in the regular table, and the reliable nuclear fee that stop the valence electrons close to the nucleus.

## Why is K bigger than Br?

Since potassium is situated at the begin of duration 3, and also bromine in ~ the end of the exact same period, potassium will have actually a bigger atomic radius 보다 bromine, and thus the biggest atomic radius that the four given atoms.

## Which has actually the biggest radius O or O 2?

O2− is larger than O due to the fact that the boost in electron repulsions the accompany addition of an electron causes the electron cloud come expand. O2− is bigger than O since O is neutral but O2− has a charge 2−. … S2− is bigger than O2− since for corpuscle with favor charges, size boosts going down a family.

## Which is larger F or F 1?

F-1 is larger than F due to the fact that F has a better positive charge and also electrons loss the nucleus.

## What is the ionic radius the s2?

The ionic radii of the ion S2–, Cl–, and also K+ room 184, 181, 138 afternoon respectively.
