What Are Valance Electrons?
In an atom, valance electrons can be found in the outermost electron shell. They are the main point of interaction between one atom and another, and are very important for the formation of molecules. Electron Shells In an atom, electrons are organized into different layers called electron shells. Each holds a set number of electrons. The structure of the electron shells is the same for all atoms, the only difference being the number of electrons the atom has in total, with more electrons filling increasingly large shells. The electrons in the outermost electron shell are called valance electrons. What Valance Electrons Do Valance electrons determine how atoms bond with other atoms and take part in chemical reactions. Atoms tend to form complete shells and will share electrons with other atoms, forming one type of chemical bond in the process. Different Chemical Bonds There are a variety of forms that these bonds can take, which vary depending on the number of electrons shared and the c
