What is matellic bonding

10. If 200. L of ammonia (NH3) are produced in the reaction between nitrogen and hydrogen at STP, how many liters of nitrogen gas is used up in this reaction?

The bonding of two atoms will most likely occur if: a more stable state can result from the union the outer shell can be completely filled all the balance electrons are removed the electronegativities of both atoms are similar
