Question

Why transition elements are called so??? Answer only if the answer is known to you.... No spam answer because on monday I am having exam.....

Answer 1

The transition metals are called such because an English chemist, Charles Bury, described them as the bunch of elements that fill inner shells (the d block fills the n-1 shell), and "bridge" the transition between stable states.

Answer 2

The term dates back to 1921, when English chemist Charles Bury referred to a transition series of elements on the periodic table with an inner layer of electrons that was in transition between stable groups, going from a stable group of 8 to one of 18, or from a stable group of 18 to one of 32.

Today these elements are also known as d block elements. The transition elements all are metals, so they are also known as transition metals.
