Why do some elements exist without ionic radius?

The elements that do not have quoted ionic radii are the noble gases. These elements do not form ionic compounds and therefore there is no crystallographic data. All of the other elements have ionic radii, these are either an "estimate" from the apparent size of the ion in different compounds, or a calculated value. Ionic radius is a useful idea but it should not be taken to literally, comparatively few compounds are truly ionic, most of them have some covalent character. The best examples of elements where the ionic radius is meaningful are the group 1, 2 metals, oxide ion and the lighter halogens.


What is the ionic radius of Mg2 and how does it compare to other ions in the same group on the periodic table?

The ionic radius of Mg2 is smaller than that of other ions in the same group on the periodic table.


Why do some elements not have a value for ionic radius?

Some elements do not have a well-defined ionic radius because their ions may have varying charge states or coordination environments which affect their size. Additionally, experimental challenges in measuring the ionic radii of certain elements may also contribute to the lack of precise data for these elements.


What is the trend for ionic radius for medals?

The trend for ionic radius across the metals is that as you move down a group on the periodic table, the ionic radius increases. This is because as you go down a group, the number of electron shells increases, leading to larger atomic size and hence larger ionic radius.


How does ionic radius change as you move down and across the periodic table?

As you move down a group in the periodic table, the ionic radius tends to increase due to the addition of new electron shells. Across a period from left to right, the ionic radius generally decreases as the increasing nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller radius.

Compounds contains an ionic bond?

In general, when an element in group 1 or group 2 combines with elements in group 16 or group 17, ionic bonds are formed between the two elements.


Is Li have the smallest ionic radius?

No, H+ ions are the smallest (proton size), hydrogen atoms and even Li+ ions are smaller than Li atoms.


What is true of the ionic size of the elements in a group as one from the bottom to the top in that group?

Ionic size increases from top to bottom within the group.


Which element has the largest radius?

francium has the largest ionic radius


What elements have an ionic radius equal to the atomic radius?

a) Sc,Ti,V,Crb) Na,K,Rb,Csc) B,Si,As,Ted) F,Cl,Br,Ie) Na,Mg,Al,SiThe correct answer of these options is a) Sc,Ti,V,Cr because they are the closest elements to each other in the periodic table.


Which ion has the smallest ionic radius Mg2 plus or Ca2 plus?

Mg2+ has the smaller ionic radius compared to Ca2+ because as you move down a group in the periodic table, the ionic radius increases due to the addition of electron shells. Mg and Ca are in the same group, but Ca has more electron shells than Mg, resulting in a larger ionic radius for Ca2+.


Which pair of elements is more likely to form ionic compounds?

Group 1 or group 2 elements with group 16 or group 17 elements. In general, if the electronegativity difference between the two atoms is more than 1.7 in Pauling's scale, then the two atoms form ionic bond.
