What does n stand for in physics?
n is the principal quantum number and represents the energy level or electron shell in which an electron resides. For example - Say you have an Oxygen atom, which has 8 electrons. It's electron configuration is 1s2 2s2 2p4. The 2 in 2p4 is the principle quantum number, n. The s is another term dealing with angular momentum and the 4 is the number of electrons.
How is the shape of an electron cloud determined?
It is a surface of constant probability i.e. an electron is just as likely to be found in a small volume anywhere around this surface. Energy sublevel
The spin quantum number of an electron can be thought of as describing?
direction of electron spin
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.
What is the quantum number that describes the most probable distance from the nucleaus that an electron resides?
Distance depends on the principal quantum number n.
What is the first quantum number of a 1s2 electron in phosphorus?
The first quantum number (n) represents the energy level (shell), so for a 1s2 electron, it would have a value of 1.
Which number represents the shape of an electron subshell?
The shape of the electron cloud is determined by the secondary quantum number. The first is n, or the energy level, the second is the sublevel, the third is the specific cloud, and the fourth is the spin.
In many-electron atoms which quantum numbers specify the energy of an electron?
the quantum number n determines the energy of an electron in a hyrdogen atom.
What is a quantum number?
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
What information does the first quantum number of an electron give?
The energy level the electron is in
What information does the first quantum number if an electron give?
The energy level an electron gives
What does the n represent in the quantum model of the atom?
n is the principal quantum number and represents the energy level or electron shell in which an electron resides. For example - Say you have an Oxygen atom, which has 8 electrons. It's electron configuration is 1s2 2s2 2p4. The 2 in 2p4 is the principle quantum number, n. The s is another term dealing with angular momentum and the 4 is the number of electrons.
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 the definition of quantum number?
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
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.
What does the quantum number represent?
represents the spin of the electron.
What is the principal quantum number value for the highest energy electron in carbon atomic number 6?
The principal quantum number for the highest energy electron in carbon would be 2. It is easy to spot this, since carbon exists in row 2 of the period table. The row in which an element resides always shows the highest value of n, or the principal quantum number, that an electron can reside in.
