Once the amount of mass in the helium core reaches about 8% of the star mass (the Schonberg-Chandrasekhar Limit), the density becomes so high that the core no longer acts like a perfect gas. It becomes degenerate.
What else can I help you with?
Does helium have the maximum number of valence electrons in its outer shell?
Yes it does. Helium has 2 electrons in the s orbital. A s orbital can hold a maximum of two electrons.
What is the maximum number of electrons that can be placed in a Lewis dot diagram?
Eight, except for helium, which has a maximum of two.
How do neutron stars form?
When a medium-size star runs out of fuel (hydrogen to fuse into helium), it will collapse on itself. It has a large enough mass that it can push past the resistance from electron degeneracy pressure. When it collapses more, it will get stopped by neutron degeneracy pressure. It will settle at a star that is about 20 kilometers in diameter. The star fuses protons with electrons, and these form neutrons to make a kind of "neutron soup".
What is degeneracy in linear programing problem?
the phenomenon of obtaining a degenerate basic feasible solution in a linear programming problem known as degeneracy.
Degeneracy in transportation problem?
Degeneracy in a transport problem arises when the number of occupied cells is less then: (number of columns + number of rows)-1
How many electron orbitals does helium have?
How many atoms / electron clouds does helium have ?
How can such degeneracy be removed?
Degeneracy can be removed through various methods depending on the context. In physics, for instance, applying an external field or perturbation can lift the degeneracy of energy levels. In optimization problems, introducing additional constraints or objectives can differentiate otherwise equivalent solutions. In general, breaking symmetry or introducing asymmetry often plays a crucial role in resolving degeneracy.
How to calculate the degeneracy of a system?
To calculate the degeneracy of a system, you need to count the number of ways the system can be arranged while still maintaining the same energy level. This involves considering the different possible configurations or states that the system can exist in. The degeneracy is a measure of the multiplicity of these states.
What is exchange degeneracy in quantum mechanics?
Exchange degeneracy in quantum mechanics refers to the phenomenon where multiple particles with the same properties (such as electrons in an atom) are indistinguishable from each other, leading to the degeneracy of energy levels. This occurs due to the symmetric nature of the wavefunctions describing the particles, which do not change if the particles are exchanged. Exchange degeneracy plays a crucial role in determining the structure and properties of atoms, molecules, and other quantum systems.
What is spin degeneracy?
Spin degeneracy refers to the multiple possible configurations of electron spin in a given energy level in an atom. Each electron in an atom can have one of two spin orientations, either +1/2 or -1/2. This results in a spin degeneracy of two for each energy level.
How to overcome degeneracy in transportation problem?
To overcome degeneracy in a transportation problem, one common approach is to introduce a small positive epsilon value to the supply or demand values, ensuring that all basic variables are positive. Alternatively, the Modified Distribution Method (MODI) can be used to identify and adjust the solution, allowing for a feasible solution without degeneracy. Ensuring that there are enough routes or allocations can also help in resolving any issues that arise from degeneracy.
Is white drawf bigger than a nertron star?
Simply, neutron star is a big nuclear - of 10km radius and solar mass (mass density about  1017- 1018 kg/m3). The material in a white dwarf is supported by electron degeneracy pressure. The physics of degeneracy yields a maximum mass for a non-rotating white dwarf, the Chandrasekhar limit-approximately 1.4 solar masses-beyond which it cannot be supported by electron degeneracy pressure. The density of white dwarf is - 109 kg/m3. So its radius is much bigger 10km, but the mass can be less, as well as bigger of solar mass.
