Neutrons

Neutrons

electrically neutral elementary particles found in all atomic nuclei except light hydrogen; the mass is equal to that of the proton and electron combined and they are unstable when isolated from the nucleus, undergoing beta decay. Slow, thermal, epithermal, and fast neutrons refer to the energy levels with which the neutrons are ejected from heavier nuclei during their decay.

Is there any difference between different fertilizers?

... elements from both sources. For example, whether nitrogen from organic or chemical fertilizer contains nitrogen atoms with same number of protons, neutrons and electrons. I think food produced by using organic and chemical fertilizer is almost same if we avoid the usage of harmful pesticides. Only ...

Do PFC Memory neutrons form latches

Hello, I just learned from this paper, neuron activity related to short-term memory, that some neurons in the pre-frontal cortex fire rapidly in the cue phase of an experiment and not during the delay. Others fire during the delay and not during cue. Others fire during both. I also read that these n...

Natural selection is proven wrong

... odd with this statement same with "sun spots might have caused a lonely neutron to fly onto a gene" well this one is just wrong. Neutrons cant move so freely without some kind of catastrophic effect "chemicals in the atmosphere might have fallen onto a gene" why not, ...

Re: Molecular gene (genome) concept scientifically untenable

... changes the nuclide. There are atomic species for an element; these species we distinguish as “nuclides”. For example P-31 with 15 protons and 16 neutrons is the stable phosphorus nuclide, which is not radioactive. When the neutron number increases to 17 it becomes P-32 and its property changes. ...
