The proton is asubatomic particlewith a positive electrical charge. They are found in every atomic nucleus of every element. In almost every element, protons are accompanied byneutrons. The only exception is the nucleus of the simplest element, hydrogen. Hydrogen contains only a single proton and...
This is where things get fuzzy—because it turns out that brown dwarfs can sustain certain sorts of fusion reactions, too. For example, they fuse deuterium, an isotope of hydrogen with an extra neutron in its atomic nucleus. Some can even fuse lithium with protons to form beryllium, and bot...

. Neutrons have no charge at all. That means the nucleus of an atom is effectively a big clump of positive charge. An electron is tiny compared to a proton, but it has exactly the same amount of charge. In fact, electrons have an opposite charge to protons (a charge of −1 or ...
The charge of one proton is equal in strength to the charge of one electron. When the number of protons in an atom equals the number of electrons, the atom itself has no overall charge, it is neutral. Electrons Can Move The protons and neutrons in the nucleus are held together very tigh...
(the antimatter form of a neutrino). This process changes a neutron in the nucleus into a proton. The second type of beta decay is beta-plus decay. In this form, the nucleus emits a neutrino and a positron (theantimatterform of an electron). This process changes aprotonin the nucleus ...
Structure of any specific atom consists of three fundamental particles named as proton, electron and neutron. Among all protons and neutrons lie in the nucleus and electrons lies in the outer shell.Answer and Explanation: The total mass of the nucleus is the sum of the mass of protons and ...
A nucleus consists of protons and neutrons. Protons are positively charged and neutrons have no charge. There is a repulsive force between protons. A force which keeps all nucleons together is called as nuclear force. Nuclear force is the strongest fundamental force....
Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes ...
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...
