Answer 1

Hey mate...... Here is the correct answer :

Based on her finding she may conclude that all the metals like the copper, aluminium ,iron ,zinc ,gold, Platinum, potassium ,sodium are good conductors of heat as well as electricity while the non metals like the ,carbon graphite, Phosphorus ,Sulphur ,iodine ,chlorine and so on are bad conductor of heat and electricity .

This is because metals have free electrons on their outermost shell which makes them good conductors of electricity for example sodium whose atomic number is 11 and 10 has 13 electrons which means that sodium is good conductor of electricity as well as heat .

But there are exceptions to non metal like the graphite or a form of carbon is good conductor of heat as well as electricity and it is used in making electrodes while the electrolysis .....

I hope that it was helpful to you.............
