Assertion : Ionisation of transition met...

Assertion : Ionisation of transition metals involves loss of ns electron before (n - 1)d electrons.
Reason : Filling of ns-orbitals takes placed before (n - 1)d orbitals.

A

If both assertion and reason are correct and reason is correct explanation for assertion.

B

If both assertion and reason are correct but reason is not correct not correct explanation for assertion.

C

If assertion is correct but reason is incorrect.

D

If both assertion and reason are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Correct explanation. ns electrons have less attraction towards the nucleus as compared to (n - 1) d electrons.

Why does in the building of an atom, the filling of 4s orbital takes place before filling in 3d orbital ?

Assertion (A) : When the transition element ionises, the 4s -orbital electrons are removed before the 3d -orbital electrons. Reason (R ) : The energy of 3d -orbital electrons is lower than that of 4s -orbital electrons.

" The sum of "ns" and "(n-1)d" electrons in Tc are : "

Many transition elements also form 3+ ions by losing one (n-1)d electron in addition to the two ns electrons except

In forming ions, the atoms of transition metals generally lose the ns electrons first, then they may lose one or more (n-i)d electrons. The 2+ ions are common for the transition elements and are obtained by the loss of the highest energy electrons from the atom except

Assertion : In transition elements radii of 5d series are virtually the same as those of the corresponding members of 4d series. Reason : The filling of 4f orbitals before 5d orbitals results in regular decrease in atomic radii.

Assertion: Mn atom loses ns electrons first during ionisation as compared to (n-1) d electrons Reason: The effective nuclear charge experienced by (n-1) d electrons is greater than that by ns electrons.
