Concept explainers
Interpretation:
The following bonds have to be arranged in increasing order of ionic character.
Concept Introduction:
An ion is a charged species formed from an atom when an atom loses or gains electron. Ions are two types – cation and anion. Cation is positively charged ion and deficient of electrons as it is formed by loss of electron. Anion is negatively charged ion and electron rich as it is formed by gaining electron.
Hence an atom is capable of gaining and losing electrons only if it is highly electropositive and highly electronegative respectively. Such atoms mainly correspond to the elements group IA, IIA (highly electropositive metals) and group VIIA (highly electronegative non-metals).
Atoms of these elements tend to form ions by losing and gaining electrons such that they form ionic bonds. Thus an ionic compound is typically a combination of metallic and non-metallic element.
For a metal and non-metal combine to form ionic bond the electronegativity difference between them must be greater than
