12. Find correct comparison of Electron Affinity, EAdloment, the energy required to remove an electron from anion, in its gaseous phase, of different elements (a) EAB>EACEAo (c) EAIKEAAKEAF (e) EAP EAN EAk Find the correct comparison of lonization Energy, IEdiememt, the energy required to remove an electron fr a neutral atoms (to make the atom a cation), in its gas phase, of the following elements (a) IEcKIEIEp (c) IEo>IEsKIEs 14. Find the correct comparison on Electronegativity values, ENclement, or N, for the elements below: (a) ENT ENAENB (b) ENc> ENFKENB (c) ENPENr EN (d) ENKEN ENR 15. The world-famous Peter Chang's Certainty Principle cleared the path to understand the electronic behavion in atom, which is based upon the facts (a) atoms, electrons, tiny (d) electrons, speed, fast are so small but the __ of electron in the atom is so (b) electrons, charge, negative (e) atoms, mass, little (e) atoms, speed, fast 16. In atoms, the discrete 3-D spatial gaps in bgtween any electronic orbitals is truly based upon the universal in between any electronic orbitals is truly based upon the universal law of repulsion is mediated and reduced by the equal or greater number of- repulsion is m electrons (a) likewise repel, neutrons, hydrogen (c) likewise repel, positrons, hydrogen trons are all negatively charged; but the extremely strong nucleus proton-proton - .-. except atoms of- (b) opposite attract-a-particles, helium (d) opposite attract, particles, the Principal Quantum number value, the n, the the energy the orbitals possess with distance from the nucleus, and (a) smaller, lower, shorter, higher (c) greater, higher, greater, lower ionization energy is required to remove electrons (b) greater, higher, greater, higher (d) smaller, higher, shorter, higher 18. The reason for Atomic Radius, ARg along the same period from left to the right side is due to electronic shield, or the effective charge, Zrg. but the number of increase. the (a) increases, same, protons (c) decreases, same, protons (b) increases, weaker, protons (d) increases, stronger, protons (c) decreases, same, electrons 19. Electron Affinity, EA, and Ionization Energy, IE, have thediagonal increase trends on the Periodic (b) opposite, atom, anion 20. In constructing Lewis Octet structures for molecules, find the correct no. of electrons between the two C-O Table. IE is the energy required to remove-from an (a) same, anion, atom (c) opposite, anion, atom , while EA is for removing e-from an (c) same, atom, anion (d) increases, stronger, protons links in CO; molecule and that of between the C-N link in HCN molecule: (a) 6, 4 (b) 4, 6 (c) 2, 6 (e) 6, 6Explanation / Answer
12. C is the right order. E.AIn< E.AAs<E.AF
13. C. I.EO > I.ESi > I.ESr
14. E. E.NP < E.NS= E.NC
