CorianÂ® is dishwasher safe. CorianÂ® is non-porous so food and most household stains wipe off with a sponge and soapy water. Stubborn stains like coffee, grape juice, ink, hair dye and food coloring rub off with an abrasive household cleanser and a Scotch-Brite pad. Even tougher stains disappear using fine grade (180-200 grit) sandpaper.
Na is a metal, and Cl is a nonmetal, so you have an ionic compound when they form. As for covalent bonds, they take place between two nonmetals ONLY. For example, you have carbon dioxide (later you will learn why you have to put di-in front of oxide).luminium oxide Al2O3 is ionic because of the presence of the metal ion, Al3+ and non-metal ion O2-. Methane CH4 is covalent as all the elements in it are non-metals. It has carbon and hydrogen, both of them are non-metals.
