In an atom, the negatively charged electrons are found outside the nucleus in different shells or energy levels. The way electrons are placed in their electron shells is called electron configuration or simply electron arrangement. Number of electrons in the outer shell of an atom is called valence electrons. These are the electrons that are either transferred or shared with other atoms during chemical reactions.
