Hello. I recently read Theodore Gray`s book "The Elements" and was extremely fascinated by the small world of atoms. I was fascinated about the structure of atoms and wanted to know more about why and how they are composed.
After studying a bit I hit a bit of a curiosity. Why don some...
What happens when hydrogen is burned up? Does it disappear? An element is defined as something that can not, in any way, be changed by a chemical reaction. But fire is a chemical reaction. What happens when hydrogen catches fire?
Funny thing is that the speed of light has been observed to be slowing down.
The speed of light is calculated using atomic clocks. Scientists have observed that, in fact, either the atomic orbits are slowing down, or the speed of light is slowing down because every once in a while you have to...
Oh, okay! Thanks! I thought so basically I had a kind-of-close idea of how that would happen. But in theory it would still be possible to make radioactive elements more stable but there just isn't any known technology to do so. right?
But how does that make sence? If you have a group of identical atoms and then a group of antimatter that has an equaly negative mass then should't they disable each other instead of exploding?
Hello! I'm new to the forum so please don't mind any mishaps.
I am very interested in the unstable radioactive elemts. I read that the thing that makes elements radioactive is ther different amounts of neutrons. Does this mean that all the radioactiive elements are radioactive just because...
