In any atom, like charges repel one another, and opposite charges attract one another. This is why two protons repel each other and so do two electrons, but a proton and an electron attract each other. In an element, the numbers of electrons and protons are equal. Moreover, since they...
The existence and importance of the proton radius puzzle, observed via a Lamb shift measurement in muonic atoms, is discussed. Possible resolutions of the puzzle are discussed. Then the broader question of the meaning of the proton radius is addressed and examples of correctly defined charge ...
Two protons combine to form a deuterium atom (hydrogen atom with one neutron and one proton), a positron (similar to an electron, but with a positive charge) and a neutrino. A proton and a deuterium atom combine to form a helium-3 atom (two protons with one neutron) and a gamma ray...
Located within the nucleus of the atom, a proton has a relatively larger mass than that of an electron but slightly smaller than that of a neutron. A proton will always have at least one positive charge. The proton is responsible for the atom's atomic number. The positive proton charge ba...
The only “reason” is that if it were even a little different, life as we know it would be impossible. The masses of the proton and neutron almost coincide. Why? If the masses of either were even a little different, life as we know it would be impossible. The energy of empty space...
In emission of an electron, a neutron is converted into a proton. Therefore, number of neutrons decreases and the number of protons increases. The neutron to proton ratio decreases. In the emission of a positron, a proton is converted into a neutron. Hen
The combination process of two intermediate size atomic nuclei to form a bigger nucleus is called nuclear fusion. High energy releases during the nuclear fusion process. This process is the reason for the high energy emission from the sun.
A zwitterion is a molecule with both positive and negative charges, but with a net charge of zero. What makes a zwitterion...
This is analogous to taking a stretched rubber sheet and placing balls of different masses upon it creating "warps" in its fabric. The bigger the mass of the ball the more extreme the warp it causes. Objects sat in spacetime are similar but in three dimensions of space and one dimension ...
Proton A proton is a subatomic particle, symbol p or p+, with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particl...
