Sr has two electrons in the highest occupied energy level
Strontium. They both have two electrons in their outermost energy level, however since the electrons are farther from the nucleus in Strontium than in Calcium, Strontium is more readily able to shed these two electrons to achieve a more stable state with it's outermost energy level being complete (with 8 electrons).
Beryllium will have the highest. Down a group ionization energy decreases.
Because, as we know that when we go across the period of the periodic table, the number of shells remain the same but the number of electrons and protons increases. So, Rb having its atomic number as 37 and Sr as 38, Strontium has got more nuclear charge as well as more electrons. As a result the first ionisation energy required to remove one electron is more in Strontium than Rubidium.

The standard unit of electric energy is the Watt Hour.
There are two electrons.
The 3rd energy level is the highest occupied energy level for chlorine with seven electrons.
Answer. 4sCa = Calcium Atomic number is 20, that means it has 20 proton and 20 electron.1s2,2s2,2p6,3s2,3p6,and 4s2, total of 20 electrons, therefore Highest occupied energy level of Ca is 4s
the period number tells which is the highest energy level occupied by the electrons
the period number tells which is the highest energy level occupied by the electrons
inner shell electrons : the electrons that are not in the the highest occupied energy level .
There are 3 valence electrons in the highest energy level of Nitrogen. Nitrogen has a total of 5 valence electrons.
the period number tells which is the highest energy level occupied by the electrons
8 electrons
inner-shell electrons
Eight.
