inner shell electrons : the electrons that are not in the the highest occupied energy level .
8: that's the meaning of "octet".
Calcium: 589,9 kJ/mol. Beryllium: 899,5 kJ/mol.
Beryllium has greater ionization energy, with 899 kJ/mol versus Germanium's 762 kJ/mol. The general trend (most prominently displayed in the representative elements) in the periodic table is increasing ionization energy across a period, and decreasing ionization energy down a group.
Radium (Ra), atomic number 88, is the most reactive alkaline earth metal. It has the most energy levels of all the alkaline earth metals therefore it's electrons are more easily taken away.
The highest occupied energy level of Beryllium is the second energy level, denoted as 2.
The highest occupied energy level in Beryllium is the 2s orbital. Beryllium has 4 electrons, with 2 electrons in the 1s orbital and 2 electrons in the 2s orbital.

7 electrons would be in the highest occupied energy level of a 7A element. Group 7A elements have 7 valence electrons, which occupy the highest energy level of the atom.
The number of electrons in the highest occupied energy level of an element in Group 15 is 5. Group 15 elements have 5 valence electrons, which occupy the highest energy level.
The electron in the highest occupied energy level is known as the valence electron. These electrons are involved in the formation of chemical bonds and determine the element's chemical properties.
Beryllium will have the highest. Down a group ionization energy decreases.
Helium has the highest ionization energy of all the elements because it has a full outer electron shell, making it very stable and reluctant to lose an electron.
The highest occupied energy level in potassium is the fourth energy level because potassium has 19 electrons, occupying the first three energy levels (with 2, 8, and 8 electrons, respectively) and the remaining electron is in the fourth energy level.
Sr has two electrons in the highest occupied energy level
A filled highest occupied principal energy level
The 3rd energy level is the highest occupied energy level for chlorine with seven electrons.
