A non metal X exists in two different forms Y and Z . Y is the hardest natural substance , whereas Z is the good conductor of electricity . Identify Y and Z
Answers
Y, that is, the hardest naturally occurring substance in the world is diamond.
The substance Z, which is a good conductor of electricity is Graphite.
Both diamond and Graphite come from Carbon, a non-metal which lacks lustre, and also does not conduct electricity.
Carbon and diamond and graphite have different properties due to the crystal structures of each.
Answer: X is carbon. Y is diamond. Z is graphite.
Explanation:
Y is the hardest known substance. We know that diamond is the hardest known substance. Hence, Y is a diamond.
Diamond is a form of carbon. So the non-metal X is carbon.
Non-metals are generally bad conductors of electricity. Carbon has a form, called graphite, which is a good conductor of electricity. So, Z is graphite.
Fun Fact:
Graphite is also used in pencils. The black shiny thing inside a pencil, which we normally call pencil lead, is actually graphite.
