Proton Questions & Answers


What is the difference between Nucleophile and Base?
One of the major differences between nucleophiles and base is their different roles in a chemical reaction. Nucleophiles are electron donors because they contain sufficient pairs of electrons that can be used to form bonds with other atoms. The activ
What are antiprotons?
The antiproton is the antiparticle of the proton. Though stable, antiprotons are typically short-lived, because any collision with a proton will cause both particles to be annihilated in a burst of energy. Predicted by Paul Dirac in his 1933 Nobel
Which type of microscopes are used to see protons?
Photons can be seen by using an electron microscope, which uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes
Are protons are neutrons of the same size?
Yes. Think of protons and neutrons as each being made up of three quarks. As far as we can tell, quarks, like electrons, are point particles -- they don't have any size at all. The quarks in each are held together by the strong force, which acts a lo
