Which orbitals of the atom are filled with electrons earlier: 5s or 4d; 5s or 4p? Why? Write down the electron

Which orbitals of the atom are filled with electrons earlier: 5s or 4d; 5s or 4p? Why? Write down the electron-graphic formula of the atom of the element with the serial number 50.

When the electron shells of an atom are filled, the principle of the minimum energy is applied, that is, when they are filled, the lower levels and sublevels that are closest to the nucleus are first filled.
Filling procedure:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, …
Therefore, as can be seen, 5s is filled earlier than 4d; 4p fills up earlier than 5s.
