WHY d-d transition is forbidden?
The d-d transitions are often forbidden in transition metal complexes because they involve the promotion of an electron from one d orbital to another of the same energy. This is prohibited due to the Laporte selection rule, which states that transitions between orbitals of the same parity are forbidden. As a result, d-d transitions are typically weak and have long absorption/emission wavelengths, making them less likely to occur.
What happens when a 3s electron becomes a 2s electron?
Any electron is not fixed to any sub-shell or orbital. If you provide sufficient energy to an electron, it would make transition to any of the higher energy orbitals and then come back to the lower orbitals radiating energy.
Why do transition metals have variable oxidation states?
Transition metals can move electrons between the outer shell and the d d orbital. For example, copper can either lose its 2 s electrons or move one of those s electrons into d orbital, which is one electron short of being full.
Which electron is on average further from the nucleus an electron in a 3p orbital or an electron in a 4p orbital?
An electron in a 2s orbital is on average closer to the nucleus.
What is the Electron Orbital Pattern of boron?
The electron orbital pattern of boron is 1s2 2s2 2p1. This means it has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, and 1 electron in the 2p orbital.
What are the vaiours types of electronic transition observed in organic compounds when exposed to Ultra violet and visible light?
The various types of electronic transitions observed in organic compounds when exposed to UV and visible light include π-π* transitions, n-π* transitions, and charge-transfer transitions. π-π* transitions involve the excitation of an electron from a π bonding orbital to a π* antibonding orbital. n-π* transitions involve the excitation of an electron from a nonbonding (n) orbital to a π* antibonding orbital. Charge-transfer transitions involve the transfer of an electron from one atom or group to another.
Which transition metal element has only one electron in its 5s orbital?
The transition metal element with only one electron in its 5s orbital is copper (Cu).
What is f-f transition?
f-f transition: the transition of an electron from an f orbital which is lower in energy to an f orbital which is higher in energy is a f-f transition.
WHY d-d transition is forbidden?

Does an electron absorb energy and make a transition to a higher energy orbital when the solution it is in is being heated?
Yes, when an electron absorbs energy (e.g., from heating the solution), it can transition to a higher energy orbital. This is because the extra energy provides the electron with the necessary boost to move to a higher energy state.
What is typical transition metal?
Typical transition elements are those elements in which d orbital is in the process of completion.d orbital can occupy 10 electrons. if in any element d orbital contain less than 10 electron it means it has incomplete d orbital and d orbital is in the process of completion. for example Sc has electronic configuration 3d1 4s2. it has 1 e in d orbital. so Sc is typical transition elements.

An electron in a 2s orbital is on average closer to the nucleus.
An electron moves from one orbital to another only when it absorbs or emits energy?
Yes, when an electron moves from one orbital to another, it does so by absorbing or emitting energy in the form of photons. This energy causes the electron to transition from one energy level to another within an atom.
Which orbital is rhodium's last electron in?
If you are filling in the electrons it will be in the 4d orbital. If you are removing electrons the first to come out is in the 5s electrons since transition metals lose 's' electrons before 'd' electrons
