What is the highest occupied energy sublevel for Strontium?
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
What is the maximum number of electrons in each of the first three energy levels for the first 20 elements?
The number of electrons that can fit into a particular energy level is 2n^2 (2 times n squared) where the energy level is n. So, for: energy level 1 we have 2 x (1x1) = 2, for energy level 2 we have 2 x (2x2) = 8, for energy level 3 we have 2 x (3x3) = 18. So, 2+8+18= 28 max. electrons in the first 3 energy levels.
How many electrons are in the nucleus of an atom with the atomic number of 20?
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
Which element has a total of 20 electrons with 2 on the outer level?
Calcium
How many Electrons in atom of calcium?
20 electronsIt has 20 protons and 20 neutrons.20 electrons
How many electrons does calcium have and where are they located at?
The atomic number of calcium is 20 as it has 20 protons and 20 electrons, they are located outside the Nucleus in the orbits known as energy levels, and are commonly known as shells of the atom. in the first energy level there are 2 electrons, in the second energy level there are 8 electron, in the third energy level there are 8 electrons, and in the fourth energy level there are 2 electrons.
Can there be more than 20 electrons in the third energy level?
no, up to 18 electrons only in the 3rd energy level.
How are the electrons arranged in energy levels?
The innermost energy level always contains two electrons and the rest are arranged in 8s. for example the energy levels of calcium- 2,8,8,2. calcium contains 20 electrons. once the energy levels are filled upto 8 electrons then we move from onto the next energy level. hope this makes sense lol :)
Can there be 20 electron in the third energy level?
Of course, between 19 and 23 electrons. Of course, between 19 and 23 electrons.

How many electrons are present in the N shell of potassium?
The 4th energy level of an atom is also known as the N shell. Potassium, which has 20 electrons as 2,8,8,2 shell configuration, has 2 electrons in N shell.
How many electrons does sulfide ion have?
A Sulfide ion has a full complement of 8 valence electrons. Sulfur is element 16. It has 6 valence electrons in its outer energy level, however, sufide is S2- so it has gained 2 electrons to fill its outer energy level.
How many minutes are in a thrid of an hour?
20 minutes
How much energy is passed from one level in the energy pyramid to the next level?
20%
What is the maximum number of electrons in each of the first three energy levels for the first 20 elements?
The number of electrons that can fit into a particular energy level is 2n^2 (2 times n squared) where the energy level is n. So, for: energy level 1 we have 2 x (1x1) = 2, for energy level 2 we have 2 x (2x2) = 8, for energy level 3 we have 2 x (3x3) = 18. So, 2+8+18= 28 max. electrons in the first 3 energy levels.
