Why does a hydrogen atom weigh less than the sum of its parts?
The hydrogen atom needs energy to split its electron off, to the measure of 13.6 volts. But because the proton + electron and the H are given without any extra free energy, the 13.6 volts is released as a photon, and the mass of the H atom is less than the sum of its parts.
Why the mass of hydrogen atom is less than the sum of masses of proton and electron?
The mass of a H-atm is less than the sun f the masses of a proton and electron. Why is this? If B represents binding energy of hydrogen atom (=13.6eV), the equivalent mass of the energy =B/c2. Hence, mass of a H-atom =mp+me-B/c2.
Why is hydrogen heavier than a proton?
Just as nuclear kinetic energy makes the nucleus heavier than the sum of the proton and neutron masses, likewise the bound electron kinetic energy makes the hydrogen atom heavier than the mass of the isolated electron and proton.
Why is an atom neutral inspite of the presence of charged particles in it?
An atom has equal number of positively-charged particles (protons) and negatively-charged particles (electrons). These equal and opposite forces balance each other. Hence, an atom, as a whole, is electrically neutral.
Why does hydrogen weigh less than a neutron?
Why is the mass of hydrogen less than of electron and proton?
the mass of Hydrogen is less then that of electron and proton because of mass defect and binding energy. And that “binding energy” is due to electric fields, in the case of an atom, as stated already.
What is the mass defect of a hydrogen atom?
A Hydrogen atom has less total energy then the separated constituents, an electron and a proton. Since it takes energy to separate the electron and the proton (once they are bound), we call it mass defect. This mass defect is equal to the binding energy that binds the electron and the proton into a Hydrogen atom.
Why is the mass of a nucleus less than the particles?
This is due to the mass-energy equivalence and a phenomenon called binding energy. Forming a nucleus releases energy because the nucleons are falling into a potential energy well. Due to Einstein’s mass energy equivalence this results in the mass of the new nucleus being less than that of the particles that formed it.
What is the mass difference between energy and mass difference?
The missing mass shows up as an increase in the kinetic energy of the electron and the release of a photon and is equal to the (mass difference) x c^2. Mass and energy are different forms of the same underlying phenomenon. A Hydrogen atom has less total energy then the separated constituents, an electron and a proton.
