Valence Essays and Term Papers

  • Valence Electrons

    Valence Electrons The valence electrons are the electrons in the last shell or energy level of an atom. They do show a repeating or periodic pattern. The valence electrons increase in number as you go across a period. Then when you start the new period, the number drops back down to one and starts increasing...

  • Valence Bond Theory

    VALENCE BOND THEORY The ‘mixing’ or ‘blending’ of atomic orbitals to accommodate the spatial requirements in a molecule is known as hybridization. Hybridization occurs to minimize electron pair repulsions when atoms are brought together to form molecules. Possible hybridization schemes: 2nd row elements:...

  • lewis dots structure

    focuses on the valence electrons, since the outermost electrons are the ones that are highest in energy and farthest from the nucleus, and are therefore the ones that are most exposed to other atoms when bonds form. Lewis dot diagrams for elements are a handy way of picturing valence electrons, and...

He suggested that atoms with fewer than eight valence electrons bond together to share electrons and complete their valence shells. While some of Lewis' predictions have since been proven incorrect (he suggested...

    except for noble gases, have valence electrons. These electrons are the ones on the outermost shell. All atoms either want to get rid of these electrons or gain enough to make a full shell. Metals, which are on the right side of the periodic table, have less than 4 valence electrons. This means they want...
