the answer is the elements Helium, Neon, Fluorine, and Oxygen are logically the least metallic.
Answer:
"The number of air molecules above a surface determines air pressure. As the number of molecules increases, they exert more pressure on a surface, and the total atmospheric pressure increases. By contrast, if the number of molecules decreases, so too does the air pressure."
The balanced equation is 2HgO --> 2Hg + O2
Solar , wind , hydropower, biomass , & geothermal
The molecule in a gas move than the molecule in a solid.
