Cl, chlorine is an element, Cl2 is the molecular form of the element. When 'free' chlorine is so reactive that it will react with itself to form diatomic (2 atoms) molecules, but it is still an element.
ClO4 is not a compound, it exists as ClO4-, which is a polyatomic ion called the perchlorate ion. Some positive ion such as potassium or ammonium must be present to balance the charge and form a compound.
To balance the redox reaction involving H2O, Cl2, P4, POCl3, and HCl, you need to first assign oxidation numbers to each element and then balance the atoms and charges. The balanced equation is: 4 H2O + 6 Cl2 + P4 -> 4 H3PO4 + 6 POCl3 + 4 HCl.
No. It's a molecular element.
Cl2 stands for chlorine gas, which is a diatomic molecule composed of two chlorine atoms bonded together. In its natural state, chlorine exists as a greenish-yellow gas with a strong, pungent odor. Chlorine is a highly reactive element commonly used in disinfectants, bleaches, and PVC production.
Yes, Chlorine is a paramagnetic element. The electron configuration of Chlorine is 1s(2)2s(2)2p(6)3s(2)3p(5) which contains an unpaired electron in the 3p orbital. Atoms with unpaired electrons are said to be paramagnetic.
