Question:
Which of the following is transition element?
A) AL
B) As
C) Ni
D) Rb
Answer:--
The transition elements are those elements having a partially filled d subshell in any common oxidation state. The term "transition elements" most commonly refers to the d-block transition elements. The 2B elements zinc, cadmium and mercury do not strictly meet the defining properties, but are usually included with the transition elements because of their similar properties.
Hence, So here Ni is transition element.

1) What is transition elements?
Answer:--
Transition elements are elements that have partially filled d orbitals. IUPAC defines transition elements as an element having a d subshell that is partially filled with electrons, or an element that has the ability to form stable cations with an incompletely filled d orbital.
2) What are transition elements. Why are they so called?
Answer:--
The transition metals were given their name because they had a place between Group 2A (now Group 2) and Group 3A (now Group 13) in the main group elements. Therefore, in order to get from calcium to gallium in the Periodic Table, you had to transition your way through the first row of the d block (Sc → Zn).
3) What are called inner transition elements?
Answer:--
The period 7 inner transition metals (actinides) are thorium (Th), protactinium (Pa), uranium (U), neptunium (Np), plutonium (Pu), americium (Am), curium (Cm), berkelium (Bk), californium (Cf), einsteinium (Es), fermium (Fm), mendelevium (Md), nobelium (No), and lawrencium (Lr).
