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.
How does ionic radius change as you move down and across the periodic table?
Ionic radius (or radii) increases as you move down a group and across a period.
Which 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.
Why are group one elements largely ionic?
Group 1 elements can easily lose its 1 valence electron and hence possess highly ionic character
What is true of the ionic size of the elements in a group as one moves from top to bottom in that group?
Ionic size increases from top to bottom within the group.

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.
What groups of elements always combine to make ionic compounds?
All metals combine to form ionic compounds.Group 1(except hydrogen),2-12, all elements form ionic compounds.then Group 13 (except Boron), Group 14-tin and lead and Group 15 Bismuth only.The above mentioned group elements form ionic compounds.
What elements have the smallest ionic radius k o s li?
Li+

Ionic size increases from top to bottom within the group.
What is the atomic radius of iodide ion?
The ionic radius of the iodide ion, I- is 206pm. It is one of the largest monatomic anions. The ionic radii of the halogen ions increase down the halogen group.
Why do elements in group 4A do not form ionic bonds?
Group-14 elements share electrons. they form covalent bonds.
Which element has the largest radius?
francium has the largest ionic radius
