Hi everyone. I'm a high school student. Recently I have been doing some past papers to prepare for the public exam in April. The reaction "ethene + steam ----> ethanol" is given and I was asked to name the type of reaction. I answered oxidation but the answer is addition. Later I asked my...
I'm in year 10 and I have been studying physics and chemistry. When I learned isotopes, I notice that for isotopes, the number of neutron is always higher than that of proton. Is it possible that there are isotopes that the number of neutron is lower than that of proton? If no, is that because...
In the process of particle decay (eg carbon-14 ---> nitrogen-14), is there any relations with radioactivity? Is it reversible? ( up quark + 2 x down quark + W positive boson = down quark + 2 x up quark + electron, so that carbon-14 turns to nitrogen-14. Is it possible that down quark + 2 x up...
There are many other particles having a larger nucleus than carbon-14 but they are stable. Why?
Why is carbon-14 radioactive even though its nucleus is relatively small? Is that the strong force applied to carbon-14 is relatively small? If yes, why?
Is the size of a nucleus proportional to...
