Quntom Theory Flashcards
Definition of automated theory
A theory that helps us to predict the location and movement of electrons around the nucleus .
Shell energy level
The shell is representing a distance from the nucleus and the place where electrons can move. The higher is the shell number the higher is the number of electrons that can exist in it.
Valance shell
The outer most shell.
Sub shell
Representing the way and the shape of movement , which are possible in every shell s p d f . S- represents special movement and it can be found in every shell. P- represents infinity movement and is found in every shell from the second shell. D - represents infinity movement and it is found from the third shell and above.
Orbitals
The path that the electrons can move on, according the sub shell. Each orbital can accumulate 2 electrons max. S 1 orbital P 3 orbitals D 5 orbitals F 7 otbitals
Quentom number
Represented by 4 values L N M S N shell number L marking the sub shell M indication for the orbital S the spin
Electron configuration
Showing the organization of the electrons of the shell and sub shell.
Aufbar principle
Atoms will complete the shells and the sub shell which is closest to the nucleus first.
Hounds rule
Electrons wIll maximally distribute themselves in the orbitals of the sub shell.
Pauls principle
2 electrons will never have the same quantum number.
Atomic size
Increase in group (more shells) Decrease in period (more protons effecting the shell)
Ionization energy
The energy required to remove a valence shell electron in the ion. Decrease in group. Increase in period ( size and octant role)
Electron affinity
The amount of energy relies when electron hits a neutral non metal. Decrease in group Increase in period ( size and octant role)
