Help with this graph please ChemActivity 90 Electron Arrangement (Where are the electrons?) Information: lonization Energy Electrons are attracted to the nucleus due its opposite charge. Therefore, energy must be supplied to pull an electron away from the leaving a positively charged species (cation) and a free electron. The ionization energy (IE) is the minimum energy required to remove an electron from an atom. Ionization energies are usually obtained experimenta y Critical Thinking Questions: 1. How many electrons does lithium have? 2. If electrons are distributed around the nucleus at various distances: a. Is the ionization energy for all of them the same? Un b. If not, which electron would have the lowest ionization energy: the electron closest to the nucleus or the electron that is farthest from nucleus? it rs lawest for the electron fart 3. a. As the atomic number increases, does the charge in the nucleus get stronger or mucwuS weaker? the cha in the nucuus %ts Stronger b. Would it require more or less energy to remove an electron as the charge changes? 4. Work as a team to predict the relationship between E and atomic number by making a rough graph of IE vs. atomic number. Do not proceed until you have finished your graph. Atomic Number
