The remaining electron must occupy the orbital of next lowest energy, the 2 s orbital (Figure 8.3.3 or 8.3.4 ). Valence electrons are responsible for the reactivity of an element. They determine how "willing" the elements are to bond with each other to form new compounds. If the valence shell of an element is full, such as with a noble gas, then the element does not want to gain or lose an electron. For example, alkali metals, which all have a valency of ...Each of the elements in this group has 4 electrons in its outer shell. An isolated, neutral group 14 atom has the s 2 p 2 configuration in the ground state. These elements, especially carbon and silicon, have a strong propensity for covalent bonding, which usually brings the outer shell to eight electrons.The valence (or valency) of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules. The concept of valence was developed in the last half of the 19th century and was successful in explaining the molecular structure of many organic compounds. The quest for the underlying causes of valence ...Valence Electrons. The electrons in the outermost shell are the valence electrons the electrons on an atom that can be gained or lost in a chemical reaction. Since filled d or f subshells are seldom disturbed in a chemical reaction, we can define valence electrons as follows: The electrons on an atom that are not present in the previous rare gas, ignoring …For representative elements, the number of valence electrons equals the group number on the periodic table. To draw the Lewis structure of an atom, write the symbol of the atom and draw dots around it to represent the valence electrons.
