Why would you classify hydrogen as a nonmetal 2017?
2 answers:
It is mainly because we have chemical compounds named Hydrides - compounds which consists of metal ions and hydrogen ion 
. So, hydrogen ion is used to "take" electron more than "give" it, as we also can see in organic compounds. Third reason is that its standard electrode potential is further higher than metals' potentials, which obviously makes it nonmetal.

Answer:
D. All of them would have the same kinetic energy
Explanation:
The expression for the kinetic energy of the gas is:-
k is Boltzmann's constant =
T is the temperature
<u>Since, kinetic energy depends only on the temperature. Thus, at same temperature, at 300 K, all the gases which are will posses same value of kinetic energy.</u>
