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.
What else can I help you with?
What do you call a compound that is held together by an ionic bond?
most ionic compounds are salt
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.
Most salts are binary ionic compounds. A.True?
True. Most salts are binary ionic compounds composed of a metal cation and a nonmetal anion.
Why do most solid covalent compounds have lower melting points than ionic compounds?
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 this in aqueous solution are ionic?
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.

What elements is most likely to form an ionic compound with potassium a.Na b.Ca c.C d.O?
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.
The name for most ionic compounds other than oxides?
A "salt" is another name for ionic compounds
Most salts are binary ionic compounds. A.True?
True. Most salts are binary ionic compounds composed of a metal cation and a nonmetal anion.

What do most ionic compounds form?
Most ionic compounds form crystalline solids. These solids have a repeating pattern of positively and negatively charged ions held together by electrostatic forces.
Most binary ionic compounds are also called salts?
No, metals are not compounds. They are elements or mixtures (alloys) containing metallic elements.
What sorts of elements react to form ionic compounds?
highly electropositive elements react with highly electronegative elements to form ionic compounds. The former forms cations and the latter forms anions and the force of attraction between the positively charged cation and the negatively charged anion is the ionic bond.
What families tend to form ionic compounds?
Ionic compounds tend to form between atoms from metals and nonmetals. This is because metals tend to lose electrons to achieve a stable configuration, becoming positively charged cations, while nonmetals tend to gain electrons to achieve a stable configuration, becoming negatively charged anions. The electrostatic attraction between these ions then forms the ionic bond.
What are most things elements or compounds?
Compounds.
