Updated On: This violates the Aufbau Principle : When adding electrons to an atom, you put them in the lowest-energy orbitals available. You have two electrons in one "2p" orbital, but none in the other "2p" orbitals. This violates Hund's Rule : There must be one electron with the same spin in each orbital of the same energy before you can put two in the same orbital.

The electrons in the half-filled "4d" orbitals don't all have the same spin. You filled the "4d" orbitals before you filled the "4p" orbitals, which are lower in energy. Ernest Z. Apr 16, To draw the orbital diagram, begin with the following observations: the first two electrons will pair up in the 1s orbital; the next two electrons will pair up in the 2s orbital.

That leaves 4 electrons, which must be placed in the 2p orbitals. Therefore, two p orbital get one electron and one will have two electrons. Hund's rule also stipulates that all of the unpaired electrons must have the same spin. In keeping with convention, the unpaired electrons are drawn as "spin-up", which gives Figure 1. When atoms come into contact with one another, it is the outermost electrons of these atoms, or valence shell, that will interact first. An atom is least stable and therefore most reactive when its valence shell is not full.

The valence electrons are largely responsible for an element's chemical behavior. Elements that have the same number of valence electrons often have similar chemical properties. Electron configurations can also predict stability.
