Periodic Table Groups

Periodic table groups are columns that organize elements based on similar properties and electron configurations. For main-group elements, the group number often indicates the number of valence electrons, which in turn affects how many electrons must be gained, lost, or shared to complete an octet.

Electron Configuration

Electron configuration refers to the distribution of electrons in an atom’s orbitals. Understanding electron configuration is essential for predicting how many electrons are needed to fill an atom’s outer shell to achieve stability according to the octet rule.

Octet Rule

The octet rule is a chemical principle that atoms tend to form bonds so that each atom has eight electrons in its valence shell, achieving a stable electron configuration similar to that of noble gases. This rule is a key driving force behind electron transfer and sharing in chemical reactions.

Valence Electrons

Valence electrons are the electrons located in the outermost shell of an atom and are primarily responsible for an element's chemical properties and reactivity. The number of valence electrons determines how an element interacts with others in order to achieve a full octet.
