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.
In what ways are a Bohr models diagram for these beryllium magnesium and calcium?
The Bohr model diagrams for beryllium (Be), magnesium (Mg), and calcium (Ca) reflect their atomic structures by illustrating the arrangement of electrons in concentric circles around the nucleus. Beryllium, with 4 electrons, has two electrons in its first energy level and two in the second. Magnesium, with 12 electrons, has two in the first level, eight in the second, and two in the third. Calcium, with 20 electrons, follows a similar pattern, with two in the first level, eight in the second, and eight in the third, and two in the fourth energy level.
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 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.
How many electrons are in the fourth level of a calcium atom?
There are 2 electrons in the fourth energy level of a calcium atom. Calcium has an atomic number of 20, which means it has 20 electrons distributed in different energy levels, with 2 electrons in the first energy level, 8 electrons in the second energy level, 8 electrons in the third energy level, and 2 electrons in the fourth energy level.
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.
What element has an electron arrangement of 2.8.5?
Phosphorus
What is the total number of electrons in the second principal energy level of a calcium atom in the ground state?
The electron configuration of calcium is: 1s2 2s2 2p6 3s2 3p6 4s2 The "second principle energy level" refers in this case to the 2s and 2p orbitals, so it would be a total of 8 electrons.

What is the electron arrangement for calcium?
The electron arrangement for calcium is 2,8,8,2. This means that calcium has 20 electrons arranged in four energy levels, with 2 electrons in the first energy level, 8 electrons in the second and third energy levels, and 2 electrons in the fourth energy level.
How many minutes are in a thrid of an hour?
