\nChlorine (Cl) has an atomic number of 17. Its electronic configuration is 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2075. The outermost shell (n=3) is the valence shell, which contains 2 + 5 = 7 valence electrons. The Cl\u207b ion is formed when a neutral chlorine atom gains one electron to achieve a stable octet configuration. The electronic configuration of Cl\u207b becomes 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076. The valence shell (n=3) now contains 2 + 6 = 8 electrons.

\nA neutral chlorine atom has 7 valence electrons. A chloride ion (Cl\u207b) gains one electron to complete its valence shell, resulting in 8 valence electrons.
\n<\/section>\n
\nIons tend to form by gaining or losing electrons to achieve a stable electron configuration, often a full valence shell (octet rule for many elements). Cl\u207b achieves a stable octet configuration in its valence shell.
