🤓 Based on our data, we think this question is relevant for Professor TBA's class at UBC.
We have to explain the trend of ionization energies of carbon.
To determine why the fifth ionization energy of carbon is so high, we need to determine which of the ions is most difficult to remove an electron from.
Ionization energy (I. E.) is the energy required to remove an electron from a gaseous atom or ion.
• First I.E. corresponds to removing the first valence electron from a neutral atom.
• Second I.E. refers to removing a second electron.
• Third I.E. refers to removing the third electron.
ionization energies further up are referred to as which electron is being removed: fourth, fifth, etc.
Explain the variation in ionization energies of carbon, as displayed in the graph.
