The electronic configuration of a chlorine atom is 2, 8, 7, indicating that it has seven electrons in its outermost shell.
The electronic configuration of a chlorine (Cl) atom is 1s² 2s² 2p⁶ 3s² 3p⁵. This configuration illustrates the distribution of electrons in the various energy levels and orbitals of the chlorine atom. More specifically, it indicates that chlorine has two electrons in the first energy level (1s²), eight electrons in the second energy level (2s² 2p⁶), and seven electrons in the third energy level (3s² 3p⁵). Chlorine belongs to Group 17 of the periodic table and is a halogen, characterized by having seven electrons in its outermost energy level, making it highly reactive in chemical reactions.
