Mg2+ ion formation [duplicate]
Why does Mg not form a Mg+1 ion, even though its second ionization energy is much higher than the first ionization energy?
(I know that an ion should resemble the noble gas closest to the element from ...

What is the maximum number of emission lines when the excited electron of a H atom in n = 6 drops to ground state?
When an electron in a higher energy state jumps to a lower energy state in Bohr’s model of hydrogen atom, it emits a photon which has energy equal to the difference in the energy between the final and ...

Electron energy shells/ levels
Essentially, I am told electron shell closest to the nucleus is the lowest energy level and subsequent shells have higher energy (I.e. those further from the nucleus).
But..... electrons in the ...

when would copper material have free electrons [closed]
If you imagine a wire of copper(note that I am not talking about electricity at all). Just only a wire of copper or copper metal or whatever full of copper atoms.
We know that each copper atom has 1 ...

How does an electrons's wave function change when it moves between energy levels?
I'm taking a class on QM and we're simulating the wave function of an electron in a box at the lowest energy level and I'm supposed to change the simulation to show the wave function for the next ...

Stability of an atom in absence of EM field
According to Bohr model of atom, electrons move up an energy level in presence of EM field and emit a photon moving down the level.
In complete absence of any external EM field, shouldn't the electron ...

What is the energy difference between inner subshells?
For exemple, in silver the energy difference between the 4d 5s subshells is ≈ 4 eV (in the ultraviolet region, that's why it has no color, etc.), but what is the energy difference between some of its ...

What does it mean when we say an atom has infinite energy levels/shells? [closed]
My chemistry teacher told that an atom has infinite energy shells according to Bohr model , where electron reside according to its angular momentum and energy.
But in lower classes/ grades I have ...
