The first layer has two, since the maximum amount of electrons you may have in layer one are two, after the first layer you may have a maximum of eight electrons per layer, so layer one has two, layer two has eight, and layer 3 has a maximum of 18. To find the maximum number of electrons each layer can have do the equation 2(n2) n=number of layers
Ionic bond is calcium's bond.
A neutral atom of calcium has 20 electrons. Electrons fill the electron shells in order of increasing energy levels, with the first shell holding a maximum of 2 electrons, the second shell holding a maximum of 8 electrons, the third shell holding a maximum of 18 electrons, and the fourth shell holding the remaining 2 electrons. Thus, three electron shells (the first three shells) would be completely filled by a neutral atom of calcium.
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.
s contains one orbital with a maximum of 2 electrons p contains three orbitals with a maximum of 6 electrons d contains five orbitals with a maximum of 10 electrons f contains seven orbital with a maximum of 14 electrons
In Argon, Potassium and Calcium, the limit is eight, but because of the overlapping energy levels, In everything from Scandium upwards, the limit is eighteen.
A p subshell can contain a maximum of 6 electrons.
Another word for a noble gas is an inert gas. These elements have the maximum electrons in their highest energy level.
The n=3 shell can hold a maximum of 18 electrons. Sulfur has 16 electrons in its neutral state, so it can accommodate 2 more electrons in its n=3 shell.
An s orbital can have a maximum of two electrons.
2 electrons is the maximum number for an single orbital.
2 electrons are found in the first electron shell.
