1. The ?-electropositive effect introduces electrons into the aromatic ring. 2. They all form X 2 " ions when reacting with electropositive metals. 3. Zinc and cadmium are electropositive while mercury is not. 4. Indeed, lanthanum is a strongly electropositive metal, comparable to calcium in electropositivity. 5. However, zinc is a more electropositive ( active ) metal in comparison to steel. 6. Doping fullerenes with electropositive metals takes place in an arc reactor or via laser evaporation. 7. The electropositive carbon will react with a negatively charged molecule and other electron-rich species. 8. As with all shark repellents, 100 % effectiveness will not be achieved with electropositive metals. 9. The third task led to development of a micro method of analysis of electropositive metals using a molten platinum bath. 10. As expected, teleosts ( bony fish ) are not repelled by the electropositive metal s cation liberation in seawater.
