The obvious answer here is that the degeneracy pressure is balanced by electrostatic attraction forces due to the positively charged nuclei. This is same idea for any bound fermion system, the degeneracy pressure that makes fermions stick together always is balanced by whatever is attracting them in the first place.

Saying "So gravity is the force ultimately responsible for the electron degeneracy pressure" seems strange contrasting with, "degeneracy pressure is what counteracts gravity in a white dwarf" (e.g.). With a normal star (e.g.), one would say that … grateful dead new songsWebuniform, spherical star. For a white dwarf star, we stated above that the electron degeneracy pressure balances the gravitational collapse, so equation (13) becomes: 𝑃𝑒= 3ħ2 15 𝑒 (3 𝑒 𝑉) 5 3 (14) This is a calculation of the electron degeneracy pressure, where m e is the mass of an electron and N e is the number of electrons. chlorhexamed spray anwendung

"WebWe like representing these energy levels with an energy level diagram. The energy level diagram gives us a way to show what energy the electron has without having to draw an atom with a bunch of circles all the time. Let's say our pretend atom has electron energy levels of zero eV, four eV, six eV, and seven eV. " - Electron degeneracy meaning

Electron degeneracy pressure - Wikipedia

Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure. The Pauli exclusion principle disallows two identical half-integer spin particles (electrons and all other fermions) from simultaneously occupying the same quantum state. The … See more Electrons are members of a family of particles known as fermions. Fermions, like the proton or the neutron, follow Pauli's principle and Fermi–Dirac statistics.

WebSep 7, 2024 · This is known as electron degeneracy pressure. If a star is not too massive, the electron degeneracy pressure prevents further gravitational collapse and a stable white dwarf is formed.
