Paramagnetism of Transition Metal Salts | Chemdemos
Paramagnetism is when a substance is weakly attracted to a magnetic field. It occurs when there are unpaired electrons in the substance. Paramagnetism is most easily observed in the salts of some of the first row transition metals (manganese through nickel). The se metal ions have unpaired electrons in degenerate d orbitals as predicted by Hund''s rule and thus exhibit paramagnetism.
What is the atomic mass of calcium chloride? | Socratic
30/6/2016· 110.98g/(mol) Let''s start with the chemical formula of calcium chloride: CaCl_2 To find the molar mass of a compound you would use the periodic table to find the molar mass of each element separately. In our case, our two elements are calcium and chlorine. Next, you have to find the molar mass of Ca (40.08 g/mol) and Cl (35.45 g/mol). From the chemical formula that I provided, we can see …
