32 electrons can fit
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.
There are four energy shells. The levels go: 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10. This is because there are 30 electrons.
An atom of calcium in the Bohr model has four energy levels. These energy levels are designated by the quantum numbers n=1, 2, 3, and 4, corresponding to the first, second, third, and fourth energy levels, respectively.
how many energy levels are filled in a krypton atom They have four levels. You always put 2 in the first. 8 in the second. 18 in the third. And I believe you are able to put 36 in the fourth level, but correct me if I'm wrong about the fourth level.
There are four electrons in the second energy level of carbon. Here's the electron configuration: 1s2 2s2 2p2 or [He] 2s2 2p2.
Bromine has four energy levels, corresponding to its electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁵. These energy levels encompass the distribution of electrons around the nucleus in various shells. The four energy levels are filled with a total of 35 electrons.
It is all to do with the Aufbau and Pauli exclusion principle. The best way to illustrate is to fill up a bus with single people. They will tend to fill the empty seats first and then start sitting two people to a seat. In the same way due to energy considerations, an orbital can only have a maximum of two spin paired electrons in it. Anymore is energetically unfavorable. The same is true with each energy level. Each one can only hold a certain maximum of electrons. 1 = 2 2 = 8 3 =18 4 = 32 So with iron which has 26 electrons, they need 4 energy levels to fit these electrons in.
The four principles of the Bohr model are: electrons orbit the nucleus in fixed energy levels or shells, electrons can jump between different energy levels by either absorbing or emitting photons, angular momentum of electrons is quantized, and the frequency of emitted or absorbed light is directly related to the energy difference between electron levels.
Calcium (Ca) has 4 energy levels, corresponding to its electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶ 4s². The first energy level can hold 2 electrons, the second can hold 8, the third can hold 18, and the fourth can hold 2 in the case of calcium. Therefore, the distribution of electrons in these levels defines the four distinct energy levels 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.
b. four valence electrons
Germanium has four electron shells. Its electron configuration is [Ar] 3d10 4s2 4p2, indicating it has electrons in the first four energy levels (shells). The first shell can hold up to 2 electrons, the second up to 8, the third up to 18, and the fourth shell holds the remaining electrons.
The arrangement of electrons in carbon is 1S2 2S2 2P2. Two electrons are in the first energy level, four in the second.1s2 2s2 2p2
There are four energy shells. The levels go: 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10. This is because there are 30 electrons.
== Answer== Generally, each sub-shell has its own energy. The sub-shells, listed in order of energy with the number of orbitals in that sub-shell, with the number of electrons each one occupies, are:1s: 1 orbital, 2 electrons2s: 1 orbital, 2 electrons2p: 3 orbitals, 6 electrons3s: 1 orbital, 2 electrons3p: 3 orbitals, 6 electrons4s: 1 orbital, 2 electrons3d: 5 orbitals, 10 electrons4p: 3 orbitals, 6 electronsetc.So, in the first four separate energy levels or sub-shell (1s, 2s, 2p, and 3s) there are 2 + 2+ 6 + 2 = 12 electrons. Note that in these first four sub-shells there are 6 orbitals (with 2 electrons each).
An atom of calcium in the Bohr model has four energy levels. These energy levels are designated by the quantum numbers n=1, 2, 3, and 4, corresponding to the first, second, third, and fourth energy levels, respectively.
Bromine has four valence shell electrons. It is located in Group 17 of the periodic table, which means it has seven electrons in its outermost shell (the fourth energy level). Therefore, Bromine has four energy levels, with the outermost shell containing the valence electrons necessary for chemical bonding.
