At ground zero, during the Universe’s singularity, the very first chemical element was hydrogen. All the other followed by fusing hydrogen into helium, which then fused into carbon and so on. Approximately 73% of the mass of the visible universe is in the form of hydrogen. Helium makes up about 25% of the mass, and everything else represents only 2%. By mass, hydrogen and helium combined make up less than 1% of the Earth.
What is the most beautiful molecule?

Why does ozone smell?
The smell of ozone is very sharp, often described as similar to that of chlorine. This is why you get that “clean” smell sensation after a thunderstorm. 2. The only two non-silvery metals are gold and copper. A metal is an element that readily forms positive ions (cations) and has metallic bonds.
Which metals absorb light?
Most metals’ electrons reflect colors equally, so the sun’s light is reflected as white. Gold and copper, however, happen to absorb blue and violet light, leaving yellow light. It’s worth noting here that copper is also the only metal that is naturally antibacterial. 3.
Is glass a liquid or solid?
In a glass, molecules still flow, but at a very low rate that it’s barely perceptible. As such, it’s not enough to class glasses as a liquid, but neither as a solid. Instead, chemists classify glasses as amorphous solids— a state somewhere between those two states of matter.
