2 1. a) "Particle inside an infinite potential well" problem in 3-D, gives as one of its result the following dependency between energy and volume Ex V-3. Based on this relation what happens to energy levels when you reduce the dimensions of your object to nanolevel (start to confine the movement of electrons)? (1p) 1s e mint e(r) min 428-1 (a) (b) 4 "1s r(A) b) Explain the formation of a metallic bond by using the above given diagrams. Explain then, by utilizing the typical properties of metallic bonds, why closed packed structures are typical for metals (2 p) 2s ( 1 2
c) Figure below shows the formation of sp³ hybridized orbitals. Explain briefly what happens during the hybridization, draw the corresponding energy levels and elaborate what the "driving" force behind the hybridization is in the first place. (1p) Z y (c) d) Identify the primary bonding type in the following figures based on the electron density distribution, which roughly describes where the electrons primarily are. Provide grounding for your answers (1 p)
