Question

which of the following is a transition element
a)Zn
b)Na
c)P
d)Cu
please ans with explanation

Answer 1

Explanation:

Many of the elements are technologically important: titanium, iron, nickel, and copper, for example, are used structurally and in electrical technology. Second, the transition metals form many useful alloys, with one another and with other metallic elements.

Answer 2

Answer :

$\bigstar\:\boxed{\bf{Transition\:Elements:}}$

Transition elements are the elements which lie in between s and p block elements in the long form of periodic table.

• They are called d-block elements as the last electron enters in the d-orbital.
• General electronic configuration of d block elements is given by $\tt{(n-1)d^{1-10}ns^{0-2}}$

1) Zn is the element of d - block but it is not considered as transition element as it doesn't form one or more stable ions which have incompletely filled d orbitals.

2) Na is the element of s - block.

3) P is the element of p - block.

4) Cu is the element of d - block. (Transition element)

∴ (4) is the correct answer!
