Unformatted text preview: CHP. 5 THE PERIODIC TABLE BOHR ATOM (revisited) 1. The n-levels are also called shells ( K , L , M shells for n = 1, 2, 3) There are 2 * n 2 electrons in a shell. 2. Transitions of e- : From n = 2, 3, 4, ... to the K-shell: K , K , K , .... From n = 3, 4, 5, ... to the L-shell: L , L , L , .... From n = 4, 5, 6, ... to the M-shell: M , M , M , .... A transition results in the emission of a photon: ( E ph = h ) 3. Energy of a level: E n - Z 2 /n 2 ( means proportional to or linear with.) 4. Moseley Experiment: Removed Inner e- of Elements inducing X-Ray transitions. Transition energy is linear with h Plotted Z vs. and obtained a line. Arranged periodic table with rows from left to right of increasing Z . Reading the Periodic Table 1. Existence of s-block, p-block, d-block, f-block 2. vertical columns: groups : elements in groups display similar behavior....
