two, i think recommend you check this answer not entirely sure
In a neutral atom of calcium, there are 4 energy levels that are partially or fully occupied. Calcium has 20 electrons, distributed among the 4 energy levels with 2, 8, 8, and 2 electrons in each energy level, respectively.
A neutral atom of calcium has five energy levels that are partially or fully occupied. These energy levels are filled with electrons according to the Aufbau principle, with the first two levels (K and L) being fully filled while the remaining three levels (M, N, and O) are partially filled.
hi
A neutral chlorine atom has 17 electrons. In its ground state, the highest occupied energy level for chlorine is the third energy level (n=3), which can hold a maximum of 8 electrons. Therefore, the highest occupied energy level for a neutral chlorine atom contains 7 electrons.
There are 2 electrons in the highest occupied energy level of a neutral strontium atom, as the electron configuration of strontium is [Kr]5s^2.
The electronic energy band of a http://www.answers.com/topic/crystalline solid which is partially occupied by electrons.
4 energy levels with 2, 8, 8, 2 electrons in the energy levels.
It has 2 unpaired electrons and 8 empty electron levels.
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 highest occupied energy level of Beryllium is the second energy level, denoted as 2.
The 3rd energy level is the highest occupied energy level for chlorine with seven electrons.
The valence electron shell of noble gases is full.
