How many neutrons does fermium have?
Inside a reactor there are plenty of loose neutrons floating about – this is how the chain reaction of the reactor works. Fermium 257 is great at absorbing neutrons and immediately become fermium 258….

How many electrons can be added to the 5th energy level?
As you know, a given orbital can hold a maximum of 2 electrons, which is why the maximum number of electrons that can be added to a given energy level n is twice the number of orbitals present on said energy level. This means that the maximum number of electrons that can be added to the fifth energy level is
How many protons and electrons does fermium have?
Name:Fermium Symbol:Fm Atomic Number:100 Atomic Mass:(257.0) amu Melting Point:Unknown Boiling Point:Unknown Number of Protons/Electrons:100 Number of Neutrons:157
Therefore, a maximum of 10 electrons can share the two quantum numbers n = 5,l = 2 These electrons are located on the fifth energy level, in the d subshell, i.e. in one of the 5 d orbitals shown below As a side note, you can find the number of orbitals that can exist in a subshell by dividing the number of groups in a block by 2
What does N = 5 mean on the periodic table?
In your case, n = 5 designates an element located in period 5. Next, the angular momentum quantum number, l, tells you the subshell in which the electron resides. The subshells are equivalent to the blocks of the Periodic Table.
