... ion. Detection The beam of ions is detected electronically. Ions with small m/z values are detected when the deflecting magnetic field is small. The magnetic field has to be increased in order to deflect heavier ions into the detector one after another and therefore produce a spectrum. Ar ? Relative atomic mass x Abundance Electron Configuration The electrons in atoms are arranged into energy levels which are numbered. Level 1 contain electron which are closest to the nucleus within level there are sub level s, p, d, f Each sub level consists of orbital; each orbital contains a maximum of 2 electrons Sub Shell S P D F Number of orbital in sub shell 1 3 5 7 Max number of electrons 2 6 10 14 Due to differences in shielding from the nucleus, different sub levels within a level have slightly different energies 1s<-- 2s<-- 2p<-- 3s<-- 3p<-- 4s<-- 3d<-- 4p Ionisation Energies Across a period As we move across a horizontal row e.g. Lithium--> Neon, there is a general ...
