How much energy is required to remove a proton from 5 N? (Units: MeV)
How much energy would be required to ionize(remove the final electron from) a He+ ion if the electron was in the n=2 level? Would it require more or less energy if the electron was in the n=4 level? (a) 2.18 x 10-18 J, more (b) 2.18 x 10-18 J, less (c) - 5.45x 10-19 J, more (d) 5.45x 10-19J, less (e) 5.45x 10-19 J, same
Be3+ is a one-electron ion. It is a beryllium atom that has lost 3 of its electrons. Minimum energy of a photon that would ionize this ion= -217.6 eV The wavelength of the photon that would excite Be3+ from its ground state to its first excited state= 7.56 nm Calculate the kinetic energy of the photoelectrons if radiation of 4.0 nm of wavelength falls on an ensemble of Be3+ ions.
How much energy is required to raise the temperature of 1.80 kg of cadmium from 20.7°C to 126°C?
It takes 208.4 kJ of energy to remove 1 mole of electrons from an atom on the surface of rubidium metal. How much energy does it take to remove a single electron from an atom on the surface of solid rubidium? J What is the maximum wavelength of light capable of doing this? nm
How much energy is required to cause an electron in hydrogen to move from the n = 3 state to the n = 2 state? b) If the electrons gain this energy by collision between hydrogen atoms in a high temperature gas, calculate the minimum temperature of the heated hydrogen gas. The thermal energy of the heated atoms is given by 3kBT/2, where kB is the Boltzmann constant.
The energy required to remove an electron from a surface of a solid element is called its work function. If a minimum of 360.9 kJ/mol is required to remove electrons from Al atoms on a surface of a sample of aluminum, what is the maximum wavelength (max) of light that can remove an electron from an Al atom on this surface?
How much energy does a freezer need to remove from 2.5 kg of water at 25 °C to make ice at -10 °C? Give your answer in Joules (not kilo-Joules!). Give your answer to two decimal places. Do not type the units in the box, just the numerical value.
Energy is required to remove electrons from a metal atom, M. Order the following ionization energy values, Ein, from smallest to largest, a) M + Ei1 > M+ +e- b) M+ + Ei2 > M2+ + e-. c) M2+ + Ei3 > M3+ + e- d) M3+ + Ei4 > M4+ +e-
Suppose you dope Si with arsenic. How much energy is required to remove the fifth electron from the arsenic atoms? Suppose Si is doped with Indium. How much energy is required to “break a bond” near an indium atom? Between boron and indium, which is a better p-type dopant? Make a guess and explain.
