What else can I help you with?
What the Aufbau principle state?
The principle is: electrons fill first the lower energy levels.
Why does the s orbital fill before the p orbitals?
The s orbital is lower in energy than the porbital.
What is the relationship between the t2g and eg orbitals in transition metal complexes?
In transition metal complexes, the t2g and eg orbitals are related as they represent different sets of d orbitals. The t2g orbitals are lower in energy and are involved in forming sigma bonds, while the eg orbitals are higher in energy and are involved in forming pi bonds. This difference in energy levels and bonding capabilities allows for the unique properties and reactivity of transition metal complexes.
Your student asked why the pi bonding orbitals are lower in energy than the sigma bonding orbitals.?
this is not a general rule. pi orbitals are always higher in energy than sigma orbitals due to side wise overlapping which is less effective than head on overlappig. however in atoms with atomic number less than 7 the sigma orbital due to overlapping of p orbitals is higher in energy than the pi orbitals formed due to sidewise overlapping of p orbitals
When electrons are excited out of their orbitals do they release light energy?
It takes energy to get those electrons up out of their orbitals. It is when they "fall back" and return to their orbitals that they release energy. The energy released will be electromagnetic energy, and if the energy is high enough (but not too high), it will appear as visible light. This is what is happening in a fluorescent tube when it is turned on and emitting light.
Which electrons will have the higher energy?
Electrons in higher energy levels, further from the nucleus, will have higher energy compared to electrons in lower energy levels. Electrons that are in orbitals with higher principal quantum numbers (n) will have higher energy.
What are the names of energy levels in d-d transition?
In d-d transitions, the energy levels are typically referred to as the "t2g" and "eg" levels in octahedral coordination environments. The "t2g" level consists of three lower-energy orbitals, while the "eg" level comprises two higher-energy orbitals. In tetrahedral complexes, the levels are reversed, with "e" being lower and "t2" being higher. These transitions are crucial for understanding the electronic properties and color of transition metal complexes.
What the Aufbau principle state?
The principle is: electrons fill first the lower energy levels.
How do energy differences between higher energy levels of an atom compare to lower energy levels?
They are smaller in magnitude than those between lower energy levels.
Must Electrons must fill the higher energy levels before they fill the lower energy levels?
No, electrons fill the lowest energy levels first before moving to higher energy levels. This follows the Aufbau principle, which states that electrons occupy the lowest energy levels available to them before filling higher ones.
Why does the s orbital fill before the p orbitals?
The s orbital is lower in energy than the porbital.

Is the electrons farther from the nucleus?
Yes, electrons in higher energy levels are farther from the nucleus compared to electrons in lower energy levels. This is due to the increased energy of electrons in higher energy levels.
Why don't elements of the fourth and higher energy levels follow normal sequence?
Elements in the fourth and higher energy levels don't follow the normal sequence because the energy levels can overlap and get closer together as the number of electrons increases. This causes complex interactions and splitting of energy levels, leading to deviations from the simple electron configuration patterns observed in lower energy levels.
