Explain why the first ionization energy of Ca is greater than that of K, whereas the second ionization energy of Ca is lower than the second ionization energy of K. (Select all that apply.) When K loses one electron, it achieves a noble gas configuration. When K loses two electrons, it achieves a noble gas configuration. Removal of a second electron from Ca requires much additional energy. Removal of a second electron from K requires much additional energy. When Ca loses one electron, it achieves a noble gas configuration. When Ca loses two electrons, it achieves a noble gas configuration. Arrange the following atoms or ions in order of decreasing ionization energy: Sr²+, So², Rb+, Br From largest to smallest ionization energy Drag and drop your selection from the following list to complete the answer: Sz²+ Br Rb+ Se² Explain why the first ionization energy of Ca is greater than that of K, whereas the second ionization energy of Ca is lower than the second ionization energy of K.
