The electron configuration of vanadium is [Ar.] 3d3.4s2; the "Ar." refers to the electrons of argon, and the additional notations describe further electrons. There are 2 electrons in the first shell, 8 electrons in the s... More »

Vanadium has five valence electrons. Valence electrons are the electrons that an element gives up or gains during a chemical bond with another element. Vanadium can be found five elements in from the left on the periodic... More »

The electron configuration of an atom refers to the manner in which its electrons are arranged in the atom's orbital shells and sublevels, or subshells. The orbital configuration of an atom's electrons is a primary facto... More »

Isoelectronic elements are elements that have the same electron configuration in the outermost valence shells. These elements can either be atoms or ions, and in the case of isoelectronic compounds, molecules. This simil... More »

Fluorine's electron configuration in the ground state is 1s2 2s2 2p5. This means that the electrons in the fluorine atom are in their lowest possible energy state. These electrons are held in orbitals in each energy leve... More »
