Question

Transition metals on the right hand side of the d-block occurs as sulphides because of

• A. their high electronegativity values as a result of which covalent sulphides are formed
• B. their much low electronegativity values as a result of which ionic sulphides are formed
• C. high melting point of suiphides
• D. low melting point of sulphides

Answer 1

The correct option is A their high electronegativity values as a result of which covalent sulphides are formed

Transition metals on the right hand side of the d-block have high electronegatvities.
Hence, they form covalent sulphides.
Hence, they occur as sulphide ores.
