The sulfur may boil or burn releasing sulfur dioxide which is a TOXICand CORROSIVEgas and may trigger an asthmatic attack. Iron is a good conductor of heat and electricity and can be used in electronic devices and equipment. The strength of a metallic bond depends on three things: A strong metallic bond will be the result of more delocalized electrons, which causes the effective nuclear charge on electrons on the cation to increase, in effect making the size of the cation smaller. What happens when an electric current is passed through a solution of an ionic compound? The reason is that they can involve the 3d electrons in the delocalization as well as the 4s. The signs that a chemical reaction occurs are: the glow, and the fact that a new substance (black iron sulfide) is formed which cannot be separated by using a magnet (see step 8 the demonstrationprocedure). The difference, however, is that each sodium atom is being touched by eight other sodium atoms - and the sharing occurs between the central atom and the 3s orbitals on all of the eight other atoms. The motion/agility of particles increases with the rising temperature. The best electrical conductor, under conditions of ordinary temperature and pressure, is the metallic element silver. metal.
