Chlorine has been used as a chemical warfare agent. Sources: In nature, chlorine is only found in the combined state, most commonly with sodium as NaCl and in carnallite (KMgCl 3 â¢6H 2 O) and sylvite (KCl). The element is obtained from chlorides by electrolysis or via the action of oxidizing agents. Element Classification: Halogen. Density (g/cc): 1.56 (@ -33.6 Â°C).
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.Since the p sub level should have 6 electrons to obtain the Argon noble gas electron configuration, chlorine is able to attract an electron.hlorine vs Chloride. The elements in the periodic table are not stable except the noble gases. Therefore, elements try to react with other elements, to gain the noble gas electron configuration to achieve stability.
