The noble gases were among the latest elements discovered; their existence was not predicted by Mendeleev when he published his first periodic table. Explain. In chemistry textbooks written before 1962, the noble gases were referred to as the inert gases. Why do we no longer use the term inert gases?
Answer to relevant QuestionsUsing the data in Table 18.22, calculate the mass of argon at 25oC and 1.0 atm in a room 10.0 m × 10.0 m × 10.0 m. How many Ar atoms are in this room? How many Ar atoms do you inhale in one breath (approximately 2 L) of ...In most compounds the solid phase is denser than the liquid phase. Why isn’t this true for water? Write balanced equations describing the reaction of lithium metal with each of the following: O2, S8, Cl2, P4, H2, H2O, and HCl.
