Van der Waals forces

  • Act between all atoms and molecules. Van der Waals forces are caused by the formation of temporary dipoles due to constant movement of electrons. The size of the force depends on the size of the molecule. The registration process just couldn't be easier. Electrons are attracted to the nucleus therefore energy is needed to remove them. 1st Electron Affinity is negative because energy is given out because electrons are attracted to the nucleus by effective nuclear charge. A relatively permanent change in behavior that occurs through experience. Classical Conditioning The amount of energy required to remove 1 mol of electrons from 1 mol of gaseous atoms to form 1 mol of unipositive gaseous ions (ions with a 1+ charge). M (g) ---> M + (g) + e -there is stronger nuclear chargethere is a full subshell (therefore the atom is stable)there is a half full subshell therefore there is evenly distributed charge in the atom. there is more shielding
  • the electron to be removed is spin paired (therefore there is repulsion)
  • the electron is far from the nucleus
    • When an electron is in the next subshell, Ionization Energy will lower because the outer electron is at a greater distance from the nucleus and there is more shielding from inner subshells. When there is a half full subshell in an atom, the first Ionization Energy

      O Is high because the atom is stable. Ionization Energy has positive values because energy is always required to remove an electron, it is endothermic. Comment on their strengths.

It is exothermic because electrons have to lose energy to occupy a lower energy orbital. 2nd electron affinity is always endothermic (positive) because the electron is added to an ion which is already negative therefore it must overcome the repulsion. Electron Affinity becomes more exothermic across the period because effective nuclear charge increases across the period therefore the shells of electrons are pulled closer to the nucleus so the electron must lose more The rest of the paper is available free of charge to our registered users.
