- Could you please explain to me how the first ionization energy of an atom of an element can be calculated using information from an emission spectrum? I just can't understand why the line with highest frequency is used rather than the line with lowest frequency. 181209
- The mass spectrum of chlorine show molecular ion peaks at mass/charge ratios of 70, 72 and 74. a Suggest formulae for m/e = 70, 72 and 74 b Deduce their relative abundances assuming that chlorine-35 has a natural abundance of 75% and chlorine-37 has a natural abundance of 25%. 250509
- 1. As orbitals are elliptical in shape then how is energy, velocity and momentum conserved because it is changing continously? 2. How would you explain that 4s is lower in energy than 3d? 3. According to the concept of orbitals it is explained that the 4s is greater in energy than 3d and according to the concept of orbits it tell us that 4s is in high energy orbit. How are both concepts are correct? 091008
