The order for filling in the sublevels becomes; 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d,7p.
It is based on many factors, but the easiest to understand is ENERGY. The orbitals in which the electron has the lowest energy are filled FIRST.

Inside orbitals in the electron cloud
Technetium has five electron shells.
Electron Orbitals can form a hybrid in order to achieve a more stable element: sp, sp2, sp3, sp3d, sp3d2

Orbitals. Not to be confused with orbits. They don't actually move in 'paths' either. Due to their nature, you cannot determine the exact location of an electron and still know where it will be next. (See "Heisenberg Uncertainty Principle") Orbitals actually are mathematical functions which describe the probability of finding an electron in a given space.
Into the orbitals.
In general, you use the Aufbau Principle which indicates the order in which the shells and orbitals are filled. You just have to learn it and then you can determine the electron configuration of the elements.
The electron configuration of an atom is the arrangement of electrons in the electron cloud around the nucleus of the atom. This is an indication of the different orbitals that are occupied by electrons in the atom.
The electron cloud is divided into s, p, d, and f orbitals. These orbitals also occur at different principle energy levels.
Electron shells, orbitals, and sub-orbitals.
Electron configuration for an atom is the distribution of electrons on atomic orbitals.
It is called an electron shell.
