why d-block elements elements are called as outer transition elements and f-block elements as inner transition elements?

Given: Mass of the disk, \( m_1 = 2.0 \, \text{kg} \) Radius of the disk, \( r_1 = 50 \, \text{cm} = 0.50 \, \text{m} \)...

The inner core of an atom is also calles the nucleus. It is the very dense region consisting of protons and neutrons at the center of an atom. An atom...

The Transition Metals are the elements found between the Group IIA elements and the Group IIB elements in the periodic table. The Group IIB are sometimes considered transition elements. The...

To define the d-d transition, first, we have to be familiar with the electronic structure of the d-block elements. The d-block elements are ones that have d-orbitals in addition to...

For Hydrogen Z=1, so we have that transitional energy is proportional to 1/1^2 - 1/2^2=3/4; for Helium Z=2, so the transitional energy is proportional to 2^2(1/2^2 - 1/4^2)=3/4. Hence, we...

This is because the lone pair interacts with the solvent such that the solvent align itself with ground state thus lowering energy at ground state and not at excited state.
