WebJul 3, 2024 · The Octet Rule. Noble gases have complete outer electron shells, which make them very stable. Other elements also seek stability, which governs their reactivity and bonding behavior. Halogens are one electron away from filled energy levels, so they are very reactive. Chlorine, for example, has seven electrons in its outer electron shell. WebPlant Energy.

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 ... brazil hmWebNov 1, 2024 · Electrons, like other quantum particles, can undergo a process known as scattering.
