Ionic bond is specific for metal-nonmetal combinations.
No, generally it is ionic.
Ionic
False. When a metal reacts with a nonmetal an ionic bond is formed.
Ionic bonds are bonds formed by a nonmetal and a metal atom. On the contrary, covalent bonds are molecules formed by two or more nonmetal atoms.
Ionic. The usual rule is that when you have a metal (sodium) and combine it with a nonmetal (fluorine), there is an ionic bond formed.
== It is said that when the two non-metals combine a covalent bond will formed.metal - metal = metallicmetal - nonmetal = ionicnonmetal - nonmetal = covalent ==
ionic bond conects a nonmetal and a metal. covalent bond connects a nonmetal and another nonmetal.
If the difference in the electronegativity between the two atoms is above 1.7, then an ionic bond is formed.
Cesium is a metal and fluorine is a nonmetal. When a metal and nonmetal bond, they form an ionic bond.
ionic bond
If the electrons are "stolen" from the metal by the nonmetal, an ionic bond is formed. If the electrons are shared between the metal and the nonmetal, a covalent bond is formed. If the electrons "resonate" between the metal and the nonmetal, a resonance bond is formed.
If electronegativity varies by more than 1.4 then you are most probably looking at an ionic bond. A variance less than 1.4 means, usually a covalent bond can be formed. This is a rule of thumb and is not always reliable. Metal to nonmetal; ionic. nonmetal to nonmetal; covalent.
