Which type of orbital is not allowed?
Which type of orbital is not allowed? The answer is d) 2d. Without going into too much detail, the 2d orbitals cannot exist because they are not allowed solutions to the Schrodinger equation. Simply put, the second energy shell, designated by a principal quantum number equal to 2, or n=2 , can only hold s […]

What is difference between paramagnetic and diamagnetic?
What is difference between paramagnetic and diamagnetic? Atoms with all diamagnetic electrons are called diamagnetic atoms. A paramagnetic electron is an unpaired electron. Diamagnetic atoms repel magnetic fields. The unpaired electrons of paramagnetic atoms realign in response to external magnetic fields and are therefore attracted. Why zinc is diamagnetic? Answer. Answer: Diamagnetic means the orbitals […]
What is the difference between thermal energy and temperature and heat?
What is the difference between thermal energy and temperature and heat? What is the difference between temperature, thermal energy, and heat?

How does photon interact with matter?
How does photon interact with matter? Photons interact differently in matter than charged particles because photons have no electrical charge. give up their energy via secondary interactions (mostly ionization). The interaction of photons with matter is probabilistic, while the interaction of charged particles is certain. What happens if an incident photon collides with a moving […]
