Fifth Question (:
5. Sodium is a metal and sulfur is a non-metal....why we classify them this way??Sodium is a metal as it has a valance electron of 1 that will be lost during a chemical reaction to make it stable and when it lost electron, it is positively charge. For sulfur it is a non-metal , it has a valance electron of 6 and it will gain 2 electrons during a chemical reaction to make it stable. As it gain electrons, it becomes negatively charge. In the Periodic Table, Sodium is being classified in Group (I) and they are metals. On the other hand, for Sulfur, it is being classified under Group (IV) which are non-metals. Therefore Sodium is able to conduct electricity as it is a metal and sulfur does not conduct electricity as it is a non-metal.
