Concept explainers
(a)
Interpretation:
Among the given pair,
Concept introduction:
On moving down the group, Metallic character of any metal increases so definitely Ionic character of any metal oxide increases.
Electronegativity decreases down the group, so the Ionic character of their hydride increases.
(b)
Interpretation:
Among the given pair,
Concept introduction:
On moving left to right in a period, metallic nature decreases.
Electronegativity decreases down the group, so the Ionic character of their hydride increases.
(c)
Interpretation:
Among the given pair,
Concept introduction:
On moving down the group, Metallic character of any metal increases so definitely Ionic character of any metal oxide increases.
On moving left to right in a period, metallic nature decreases.
Electronegativity decreases down the group, so the Ionic character of their hydride increases.
(d)
Interpretation:
Among the given pair,
Concept introduction:
On moving down the group, Metallic character of any metal increases so definitely Ionic character of any metal oxide increases.
Electronegativity decreases down the group, so the Ionic character of their hydride increases.
