Electronic Configuration in Groups
The outermost shells of elements in the same group have the same number of electrons, resulting in identical valence shell electrical configurations. As a result, the characteristics and chemistry of elements in the same group follow a similar pattern.
An example of the electronic configuration of elements in the same group is, Lithium(Li) and Sodium(Na) both are in the same group thus, their electronic configuration is,
- Lithium (LI) = [He] 2s1
- Sodium (Na) = [Ne] 3s1
Electronic Configuration in Periods and Groups
Electronic Configuration is the arrangement of electrons in orbitals around an atomic nucleus. Electronic Configuration of a molecule refers to the distribution of electrons in various molecular orbitals. The number of electrons in bonding and antibonding molecular orbitals of a molecule or molecular ion can be calculated from its electronic configuration.
In this article, we will learn about Electronic Configuration, Electronic Configuration in Periods, and Electronic Configuration in Groups.
