Concept explainers
(a)
Interpretation:
From the given data, compound with highest ionic character, ion with least ionic radius, atom with greatest ionization energy and oxide having high acidic character has to be identified.
Concept introduction:
Ionic character: Higher the electronegativity difference between the two atoms will results the bond is more polar (ionic).
To identify: The compound having highest ionic character
(b)
Concept introduction:
Ionic radius: The radius of an ion is known as its ionic radius. It may be a cation or an anion.
To identify: The ion having least ionic radius
(c)
Concept introduction:
Ionization energy: In gas phase, the smallest amount of energy required to remove an electron from an atom is known as ionization energy.
To identify: The atom having highest ionization energy
(d)
Concept introduction:
Acidic oxides: these are the oxides which forms acid with water and forms salt with base.
To identify: The most acidic oxide from the given set of oxides
