Ionic compounds consist of cations (positively charged ions) and anions (negatively charged ions) held together by electrostatic forces. These ions typically form a crystal lattice structure in a repeating pattern. The most common elements in ionic compounds are metals as cations and nonmetals as anions.
most ionic compounds are salt
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.
True. Most salts are binary ionic compounds composed of a metal cation and a nonmetal anion.
Solid covalent compounds have weaker intermolecular forces compared to the strong electrostatic forces present in ionic compounds. This results in lower melting points for covalent compounds since less energy is required to break the intermolecular forces holding the molecules together.
Most compounds that produce an electrolyte in aqueous solution are ionic. When dissolved in water, ionic compounds such as salts dissociate into their constituent ions, increasing the solution's conductivity, which allows it to conduct electricity. This is why most electrolytes in aqueous solution are ionic compounds.

a. Na (sodium) is most likely to form an ionic compound with potassium. Both elements are alkali metals and tend to form ionic compounds due to their tendency to lose electrons and achieve a stable electron configuration.
A "salt" is another name for ionic compounds
True. Most salts are binary ionic compounds composed of a metal cation and a nonmetal anion.

Compounds.
Most ionic compounds form crystalline solids. These solids have a repeating pattern of positively and negatively charged ions held together by electrostatic forces.
crystals :)
No, metals are not compounds. They are elements or mixtures (alloys) containing metallic elements.
True. Most salts are binary ionic compounds composed of a cation from a metallic element and an anion from a nonmetallic element.
