WebDoing so gives us bands. Now the bands represent all the possible energy eigenstates (spin states) of the valence electron of the atom. As a general example, we can consider the following situation for an atom: Say the atom has a valency 1, then its valence band will be half full. If an atom has a valency 2, then its valence band will be full. WebDec 6, 2024 · Valency is defined as the total number of electrons an atom can lose, gain, or share at the time of bond formation to get a stable electronic configuration i.e. to complete an octet. The valency of an atom can be variable in different compounds or in chemical reactions due to different bonding mechanisms. Francium (Fr) valence electrons
