What is the quantum number set of the ground-state electron that is found in helium but not in hydrogen?
The quantum number set of the ground-state electron in helium, but not in hydrogen, is (1s^2) or (n=1, l=0, ml=0, ms=0). It indicates that the electron occupies the 1s orbital, which has a principal quantum number (n) of 1, an orbital angular momentum quantum number (l) of 0, a magnetic quantum number (ml) of 0, and a spin quantum number (ms) of 0.
Do quantum numbers define the energy states and the orbitals available to an electron?
Yes, quantum numbers define the energy states and the orbitals available to an electron. The principal quantum number (n) determines the energy level or shell of an electron, the azimuthal quantum number (l) determines the shape or orbital type, the magnetic quantum number (m) determines the orientation of the orbital, and the spin quantum number (+1/2 or -1/2) determines the spin state of the electron. Together, these quantum numbers provide a complete description of the electron's state within an atom.
What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
What is a quantam state with zero spin?
A quantum state with zero spin is a state where the angular momentum of the system is zero. This means that the system has no intrinsic angular momentum or spin. In other words, it has a spin quantum number of 0.
When a hydrogen electron is in its ground state its principle quantum number is?

What is the largest principal quantum number in the ground state electron configuration of iodine?

What is the principal quantum number for the outermost electrons in a bromine atom in the ground state?
The electronic configuration of Bromine in its ground state is: 1s2 2s2p6 3s2p6d10 4s2p5. Therefore the principal quantum number for the outermost electrons in a Bromine atom is 4.

The principal quantum number for the outermost electrons in a Bromine atom in the ground state is?
It is n=4 because Br is in the 4p valence shell.
Which quantum number represents the distance between an electron shell and the nucleus?
Based on Heisenberg's uncertainty principle, there is no way possible to have a quantum number for position since the electron's second quantum number already gives you an exact value for its angular momentum.Bohr calculated the most probable radius of the electron cloud (which he mistakenly thought was an actual distance) getting the number 5.29X10-11 m.What I think the asker is speaking of is the quantum number that refers to energy level, n. Though not a physical distance it may be interpreted, using the Bohr model, how "far" away an electron is from the ground state, which some would believe (incorrectly) that this is a function of distance from the nucleus.
A quantum of energy as defined in the Quantum Mechanical Model is a?
It isn't so much a matter of there being a given "quantum of energy" as much as energy is quantized. This means that particles that behave quantum mechanical laws can only have certain values of energy and not the values in between. The most popular example of this is an electron in an atom. Quantum theory tells us that the electron can be in it's ground state energy, which has a given value, or it's first excited state, which has another given value, or any higher excited state. However, you cannot observe an electron with an energy value in between the ground state and first excited state, or between any two consecutive excited states. This is what it means to have quantized energy: only certain discrete values are allowed.
How many sublevels are occupied in an atom of sulfur in the ground state?
there is only one unpaired electron in copper
The quantum mechanical model of the atom?
"The quantum mechanical model of the atom" is a pretty vague phrase, but basically it can be thought of as the set of solutions to the Schroedinger equation HΨ = EΨ . (Yeah, that looks like the world's stupidest equation with solution H = E, but what's important to understand is that H isn't a variable or number, it's an operator. That means we don't get a single E for all Ψ, we get a collection of Es each corresponding to a different function Ψ.)
In computational quantum mechanics one of the primary goals is to calculate the ground state energy of many-body systems. Why not calculate the systems energy at 273K or 100K?
The actual goal of this particular facet of quantum mechanics is to calculate all of allowable energy states, not just the ground state. The ground state is significant though since it's the energy that the system is always trying to get to.
Is that electron moves with same and constant speed in orbit?
yeah but it depend on which quantum level it is and also on the state of the atom whether it is in excited or ground state.
Do quantum numbers define the energy states and the orbitals available to an electron?
Yes, quantum numbers define the energy states and the orbitals available to an electron. The principal quantum number (n) determines the energy level or shell of an electron, the azimuthal quantum number (l) determines the shape or orbital type, the magnetic quantum number (m) determines the orientation of the orbital, and the spin quantum number (+1/2 or -1/2) determines the spin state of the electron. Together, these quantum numbers provide a complete description of the electron's state within an atom.
