(a)
Interpretation:
The metal that has highest melting point has to be identified.
Concept introduction:
The groups 3 to 12 on the periodic table (d-block of the periodic table) are called
(b)
Interpretation:
The metal that is commonly used in construction has to be identified.
Concept introduction:
The groups 3 to 12 on the periodic table (d-block of the periodic table) are called Transition metal elements. The lanthanide and actinide series are also considered as inner transition metals.
(c)
Interpretation:
The radioactive f-block element has to be identified.
Concept introduction:
The groups 3 to 12 on the periodic table (d-block of the periodic table) are called Transition metal elements. The lanthanide and actinide series are also considered as inner transition metals.
(d)
Interpretation:
The metals in nitrogenase and acts as a nitrogen fixing catalyst has to be identified.
Concept introduction:
The groups 3 to 12 on the periodic table (d-block of the periodic table) are called Transition metal elements. The lanthanide and actinide series are also considered as inner transition metals.
