Electron affinity is the energy change that occurs when an electron is added to a gaseous atom. For most atoms, would you expect the sign for this energy change to be positive (energy required) or negative (energy released) and why? O Negative, because energy is required to add an electron. O Negative, because energy is released to add an electron. O Positive, because energy is released to add an electron. O Positive, because energy is required to add an electron.

For a Hydrogen Atom these energies can be calculated by the following equation: 1 Latulan he - - ATelacirun- R n Ru-2.179 x 10-18J (Hydrogen atom) The Helium Ion, Het, has energy levels similar to those of the hydrogen atom. The helium ion, like the hydrogen atom, has only one electron. This eliminates electron-electron interactions, and allows us to calculate the energies of the electron in each of the energy levels (n = 1, 2, 3 .) of the helium ion: 8.7149 x 10-18J Eçloetron - RH - 8.7149 x 1018J n (Helium Iou) The energy released as a photon (Ephoton), when the electron in the helium ion (He*) transitions from higher energy levels to lower energy levels in the ion, can be calculated by the equation: 1 + Ephoton - hc -- AEelectron - RHet ----- n?

Cyanamide is a compound containing two hydrogen atoms and some amount of C and N. There are a total of 5 atoms in the compound. The products of combustion were found to be CO2, NO2, and H2O. If the enthalpy of combustion for cyanamide is – 671.9 kJ/mol and the enthalpy of formation is 58.8 kJ/mol, what is the chemical formula for cyanamide? ( ΔfH (CO2) = - 393.51 kJ/mole; ΔfH (NO2) = + 33.10 kJ/mole; ΔfH (H2O) = - 241.826 kJ/mole)
