Web3. Explain the difference in first ionization energy between lithium and beryllium. Li Be because Li has less ENC than Be 4. The first and second ionization energies of magnesium are both relatively low, but the third ionization energy requirement jumps to five times the previous level. Explain. Mg +2 has the noble gas configuration of [Ne]. WebElectron configuration notation eliminates the boxes and arrows of orbital filling diagrams. Each occupied sublevel designation is written followed by a superscript that is the number of electrons in that sublevel. For example, the hydrogen configuration is 1s1, while the helium configuration is 1s2.
