Concentration of elements in the ocean relative to the total concentration in the bulk silicate Earth (BSE). Of all the elements, only Cl and Br have a significant fraction in the ocean (see inset), indicating the extreme hydrophilic character for the heavier halogens.
Chlorine is an element in the periodic table which is denoted by Cl. It is a halogen (17 th group) in the 3 rd period of the periodic table. The atomic number of chlorine is 17; thus, it has seventeen protons and seventeen electrons. Its electron configuration is written as 1 s 2 2 s 2 2 p 6 3s 2 3p 5. Chloride has achieved the Argon electron configuration, therefore, stable than the chlorine atom. â¢ Chloride ion is attracted to positively charged electrodes or other positively charged chemical species, but chlorine does not.
