	I was wondering if any one new the "specific heat capacity" of Hydrogen, H ? I found on one site it said it was 14.304 J / g / K Does any one know if this is true? I didn't know if it was correct because it would be more than that of water 4.18 J / g / K.

The specific heat of Hydrogen will depend on it's density, pressure, and temperature. But for conditions at for which you are familiar with, where you can say it's an ideal diatomic gas, then the specific heat would be approximately 5/2*R which is about 20 J/g/K. So, I'd say the 14 is probably right. Keep in mind a gram of H2 is 12 liters of gas under standard conditions!

What are the characteristics of the elements as followed: Hydrogen, Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium?

Hydrogen takes on the properties of a liquid metal only at a very high pressure. Under normal conditions, hydrogen behaves as a nonmetallic gas.
