Can ionizing radiation cause a proton to be removed from an atom?
I understand that light of 100nm or less can cause an electron to be ejected from an atom, creating an ion.
Could it instead cause a proton to be ejected from the atom? (This would also be "ionizing")
Does it matter whether the atom is stable? If an…

Ionization Energy and Bohr
I was having problems with ionization energy - but all it is is the energy required to remove first electron that pops off right? In the case of Bohr's atom, there's only one electron, so it's that electron in it's ground state. In the case of a…

is it possible to mechanically ionize a substance?
Is it possible to mechanically ionize a substance? Eg. by pressing it through a molecular sieve or by vibration or mechanical waves. Or anything else? I am talking about breaking chemical bonds through mechanical force and not chemistry.

If energy is required to add the electron to gaseous atom then why further energy is required to remove it?
If energy is required to add the electron to gaseous atom (electron affinity - in case of noble gases) then why is further energy (ionization energy) required to remove it?
The reason for ionization energy to be positive is that it is energy…

When air is ionised, which component gases are actually ionised?
Air is a mixture of O2, N2 etc. Which gases are ionised at STP, and is there a different level of ionisation for different gases?

Ionization energy comparison
I'm a bit confused about this part since it doesn't specifically mention it in my book as far as I've read.
But let's say if I have to compare the ionization energy of the hydrogen atom to the ionization energy of Be$^{3+}$, I know that the…

Ionization energies of atoms while bonded
Is the ionization energy of an atom different when it is in a bond or in a crystal?
For instance the ionization energy of H is 13.6 eV. Is it different when bonded with O in water? Another example is the ionization energy of Si in a crystal.
