How does the energy in the third shell of an atom compare to the energy of an electron in the first shell of the same atom? How does the energy on the third shell of an atom compare to the energy of an electron in the first shell of the same atom?
Outside the nucleus of an atom: The volume of the rest of the atom (surrounding the nucleus) is occupied by the other type of sub-atomic particle, which is called anelectron, or rather (in all cases except forhydrogen) electronsbecause there are many electrons per atom. ...

Cmay be less or more than zero depending upon the nature of orbital involved Dless than zero.Submit The total energy of an electron in an atom in an orbit is −3.4eV. Its kinetic and potential energies are, respectively: A3.4eV,3.4eV B−3.4eV,−3.4ev C−3.4eV,−6.8eV D3.4...
When an atom undergoes electron capture, the daughter nucleus produced will have one less proton and one more neutron than the parent nucleus. This is... Learn more about this topic: Radioactive Decay | Formula, Types & Examples from
(f) For a carbon atom, the binding energy of an electron is of the order of a few electronvolts.Compton's theory assumes that the electrons are not bound in the atoms but are free.Suggest whether, for 30 keV photons, this assumption is justified... [2][Total: 20] 相关知识点: ...
An electron is a negatively charged subatomic particle that can be either bound to anatomor free (not bound). An electron that is bound to an atom is one of the three primary types of particles within the atom -- the other two areprotonsandneutrons. ...
In an atom , an electron is moving with a speed of 600 m/s with an accuracy of 0.05% . The certainty with which the position of the electron can be located is
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 a new element, while adding a neutron makes an isotope, or heavier version, of that atom. ...
