Question

What are the d-block elements called?

(a) Inner transition elements

(b) Alkali earth metals

(c) Transition elements

(d) Noble gases

I have been asked this question in unit test.

Query is from Electronic Configurations of Elements and the Periodic Table topic in chapter Classification of Elements and Periodicity in Properties of Chemistry – Class 11

Answer 1

The correct answer is (c) Transition elements

For explanation I would say: The d-block elements are called transition elements as the electrons are energetically filled. The exact meaning of transition elements is that elements have either partially or fully filled subshell or can actively cations by losing electrons.
