Ionisation energy Definition and 13 Threads

I'm a huge Star Wars fan and it just occurred to me, that the ion weapons used to disable droids, ships and other electronics would cause serious harm as well, to living beings, if they got accidentally hit by a bolt. Ionized radiation can give a person cancer, and the amount of microsieverts to...

Homework Statement The question's in the screenshot attached. Homework EquationsThe Attempt at a Solution I don't know why (B) would be right. I feel like since for Mg's second ionisation energy, it is going from Na to Ne, and Ne is another energy level, Mg's 2nd ionisation energy should be...

I'm looking at fe ionisation. Wherever I look I get similar values. Probably because everybody just keeps reusing published values... I think the value for the 24 th level is incorrect but I'm not sure how to validate this. The published value is 195200 but I think it should be more like...

Hello all, I'm just learning about beta decay and the emission of beta particles. I have come to an understanding that this is ionising radiation because it has the ability to remove electrons and turn the molecules it interacts with into ions. I've looked on the Internet for this information...

Why is it easier to remove an electron from p orbital than s orbital. I thought P orbital have higher energy so more energy is require to remove a electron from P orbital.

Hi! I saw something on my lecture notes that I don't really understand. It reads "Rare gases have filled s and p-sub-shells, which leads to a spherically symmetric charge distribution. Since electrons are indistinguishable they take on a common wavefunction. The point is that this results in a...

So, as a matter of interest, I tried predicting the ionisation energy of a Hydrogen atom according to classical electrostatics. I started from the point of escape velocity, with Ve=√(2kq1/r) The following bit I think is wrong, but fetches an interesting result. As E=1/2mv2, the analogous...

Because, if a higher electronegativity means a higher attraction to electrons an atom has, wouldn't that mean that a greater energy would have to be put into ionise an atom with a higher electronegativity?

Hello! Not sure if this is the right place to post this question. It concerns ionization energies. A certain amount of energy is needed to eject an electron, if the energy provided exactly matches the workfunction, then the electron has zero kinetic energy. If it is some amount greater than...

Hi, I've a question that shows me a diagram for wavelength, there's 4 of them 11.1 x 106 10.5 x 106 9.7 x 106 8.4 x 106 then it asked me to determine the ionisation energy of hydrogen in KJ mol-1 by using the above spectrum. From what i know E = hf f = c/lambda lambda being the...

Homework Statement The wavelengths λ of spectral lines produced by the Hydrogen atom are given by the expression: . Calculate the Energy in eV required to ionise the atom Homework Equations p=h/\lambda The Attempt at a Solution n2 = 1 and n1 = infinity, therefore \lambda=1/R. E = p2/2m...

Hi, may i know why is the first row of the d orbitals (starting from scandium to zinc) should such a weird graph of ionization energy against number of protons? Here the proton number 22 element (titanium) has a higher ionization energy than the proton number 23 element (Vanadium). It is not...

Why is the first ionisation energy of chlorine is higher than that of sulphur ? i am having trouble with the questions above please help thanks :smile:
