Hi Yuli, Have you made any attempts or do you have any ideas of how to solve task 2? What is the general equation for determining the probability density in quantum mechanics? Please give a bit more of your thought process so we can help you out! Cheers, Kamas

Hi pugtm, Don't freak out if problems occasionally seem easy - sometimes they are! Knowing that h*c=1240 eV*nm, (1240 eV*nm)/(298 nm) = 4.2 eV Let's check this answer using a different method: So you know that the wavelength of an incident photon is 298 nm, and we can determine the...

Hi Miike, A covalent bond is one in which electrons are shared between two atoms. Fluorine is more electronegative than iodine, meaning that the Sn-F bond is more polar than the Sn-I bond. Because iodine does not pull on the electrons as strongly as fluorine does, the Sn-I bond has more...
