How does the Pauli exclusion principle help us determine where an electron is within the atom?

It really says that no two electrons can have the same 4 quantum numbers. Effectively that means that one orbital can only hold 2 electrons at most.
the first answer is absolutely correct but if used in the context dealing with a neutron star, this is a law of physics that prevents a neutron star from further collapse it simply states that no 2 neutrons can occupy the same quantum state simultaneously

∙ 11y agoPauli exclusion principle, if i remember right is that 2 electrons cant have the same spin in an orbital. so with its spin you can tell the placement within the orbital

Which describes electron probe microanalysis to determine the elemental composition of glass?
Electrons excite atoms in a sample, which emit X rays characteristic of the elements within the sample.
Which rule explicticly states that each orbital of an atom can fit two electrons in oppsite spins?
Hund's rule: "Two electrons cannot share the same set of quantum numbers within the same system." There is room for only two electrons in each spatial orbital (according to Pauli exclusion principle, mentioned in question).
Why are the first ionisation energies of sulfur and aluminium lower than those of phosphorus and magnesium?
Well between Magnesium and Aluminium there is a change in sub-shells as the outer most electron in Aluminium is within the p-shell, where as the Magnesium is within the s-shell . This means the electron within Aluminium is further away from the nucleus, in addition there is more shielding involved. Consequently the electron needs less energy to force it away phosphorus and sulphur and are in the same shell , however sulphur contains a extra electron to phosphorus. This extra electron is paired with another electron which in turn as the both are negatively charge repel each other , making it easier to force the electron out :)
Define electrochemical corrosion?
Electorchemical corrosion is corrosion that is sped up due to electron movement, within the chemicals.
What is the name of machine used for making subatomic particles move faster?
Particle accelerator
Why does the pauli exclusion principle include the word exclusion?
The Paul Exclusion Principle states that "No two electrons in an atom can have identical quantum number." It includes the word exclusion because each unique quantum state is exclusive to a single electron.
Do the electrons within the electron cloud have different amonts of energy?
Of course, if any two were in the same state it would violate both fermi statistics and the pauli exclusion principle.
What does the Heisensberg uncertainty principal state?
The Heisenberg Uncertainty Principle states that it is impossible to know both the position and momentum of an electron within at atom's electron cloud. As soon as you determine one property, the other is rendered invalid by your means of measurement.
The idea that people within a state can and should determine the laws within that state is referred to as?
The idea that people within a state can and should determine the laws within that state is referred to as popular sovereignty. Popular sovereignty is the principle that the people in a state can determine the laws within that state.
Why is bernoulli's principle a principle and not a law?
There is confusion over this because "law" and "theory" mean very different things in every day life compared to science. A "law" is just an outdated term for "theory." Theories are explanations of a phenomenon that have undergone rigorous experiments by scientists. A law is no more scientifically valid than a theory in science. A principle is usually more specific than a theory. For instance, you have the Theory of Quantum Mechanics and within that, you have Pauli's exclusion principle.

Electrons excite atoms in a sample, which emit X rays characteristic of the elements within the sample.
How does one determine the location of an atom's electrons using the quantum theory?
Due to Heisenberg's uncertainty principle one can never know the position of an electron to an arbitrary precision. We can only use quantum mechanical probability densities to estimate it's position. Or we can measure it's location, but that only tells us where it was and can not tell us where it is or how fast it is moving.
What do you call a collection of electron orbitals within an atom?
It is called an electron shell.
What are the divisions within a shell called?
A subshell is a subdivision of electron shells.
What is the rule that states that as the speed of a moving fluid increases the pressure within the fluid decreases?
Bernoulli's Principle
What principle states that no two species can occupy the same niche in the same habitat at the same time?
The habitat is where an organism lives and has many different organisms within it. The niche is the purpose that organism fulfills in that habitat. No two species can occupy the same niche in the same habitat due to competition for that role.
What is similar to an electron and has positive charge?
Nothing is identical to an electron as electrons obey the Pauli exclusion principle and they are all different. == Another electron. All electrons have the same elemental structure. Certainly when we evaluate them in "small regions" of space, their momentum is uncertain. But intrinsically, all electrons are alike. And somewhere there is footage of Murray Gell-Mann saying exactly that. He has a pretty good grip on stuff like this. The Nobel Prize he won in Physics is just icing on the cake.
