Explanation: The ionic radii the cations follow the exact same trends together atomic radii. They boost from top to bottom and also from ideal to left in the periodic Table. Thus, the ion v the largest radius is closest come the reduced left corner of the regular Table, and also that is the K+ ion.

You are watching: Which of the following has the largest ionic radius


What facet has the biggest ionic radius?

As deserve to be viewed in the figures below, the atomic radius rises from height to bottom in a group, and decreases from left come right throughout a period. Thus, helium is the the smallest element, and also francium is the largest.


Which the the following ions has larger ionic radius?

Hence P3− is largest amongst mentioned options.

What is the ionic radius that Mg2+?

Metallic, Covalent and also Ionic Radii(r)*

Atom/Ionr(pm)
Lu3+86
Mg160
Mg2+72
Mn137

Do friend predict the the ionic radius that Sr2+ is larger or smaller sized in dimension than the ionic radius of Mg2+?

Hence, indigenous the digital configuration the Mg2+ ( ) and that that Sr2+ (), the Sr^2+ ion is much larger and has many much more intervening shells than Mg2+. Hence it follows that as we relocate down team 2, we expect that the ionic radius should rise in accordance through the reason provided above.


Why is K bigger 보다 Br?

Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the biggest atomic radius of the 4 given atoms.


Which element has a bigger ionic radius than atomic radius?

Anion or an unfavorable ion: An atoms gains one or much more electrons to type an anion, make the ion bigger than the neutral atom. Nonmetals often kind anions, so their ionic radius tends to be bigger than your atomic radius. This is particularly noticeable because that the halogens.


What facet has the the smallest ionic radius?

Which element has the the smallest atomic radius? Explanation: Helium has the the smallest atomic radius. This is as result of trends in the routine table, and also the reliable nuclear fee that holds the valence electrons close to the nucleus.


Which ion is bigger Ca2+ or Mg2+?

Cations are smaller sized than their parent atoms, and also so the Ca2+ ion is smaller sized than the Ca atom. Because Ca is below Mg in group 2A of the periodic table, Ca2+ is larger than Mg2+. Consequently, Ca > Ca2+ > Mg2+.


Which is larger Cu+ or Cu2+?

Cu+ is bigger than Cu2+. Cu2+ has a smaller sized cationic radius because of stronger hold of the cell nucleus on the remaining 27 electrons after the ns of two as compared to Cu+ where just one electron is lost and also the hold of cell nucleus is less.


Which that the following ions has actually minimum ionic radius?

The ionic radius that Ni2+ is minimum.

What has the highest value in the ion?

Which one of the adhering to ions has the highest possible value the ionic radius? This have the right to be defined on the communication of z/e, wherein as z/e proportion increases, the dimension decreases and when z/e ratio decreases the dimension increases. Z is atomic number and also e is number of electrons. The correct option is C.
