What is the value of the quantum number n for a spin-down electron in a 2s orbital?
The quantum number ( n ) represents the principal quantum number, which indicates the energy level of an electron in an atom. For an electron in a 2s orbital, the value of ( n ) is 2, regardless of the electron's spin orientation (up or down). Thus, a spin-down electron in a 2s orbital also has a principal quantum number ( n = 2 ).
An electron in the second main energy level and the second sublevel is described by the symbols?
The electron in the second main energy level and second sublevel is described by the quantum numbers n=2 (main energy level) and l=1 (sublevel), which corresponds to the p orbital. The set of quantum numbers for this electron is 2p.
What does the third quantum number (l) describe?
The specific orbital within a sublevel- apex
Which orbital in lithium is an electron transfered to form an Li ion?
An electron is transferred from the 2s orbital of lithium to form a Li ion. This results in the formation of a Li+ ion with a filled 1s and empty 2s orbital.
How many orbitals of 2s?
There is only one 2s orbital in an atom.
What is associated with more energy a 2s or a 3s orbital?
A 3s orbital is associated with more energy than a 2s orbital. This is because the principal quantum number (n) is higher for the 3s orbital compared to the 2s orbital, resulting in higher energy levels.
What is the value of the quantum number n for a spin-down electron in a 2s orbital?
The quantum number ( n ) represents the principal quantum number, which indicates the energy level of an electron in an atom. For an electron in a 2s orbital, the value of ( n ) is 2, regardless of the electron's spin orientation (up or down). Thus, a spin-down electron in a 2s orbital also has a principal quantum number ( n = 2 ).
What is the third quantum number of a 2s2 electron in phosphorus 1s2 2s2 2p6 3s2 3p3?
The third quantum number of a 2s electron in phosphorus is 0, because the 2s orbital has zero angular momentum. The quantum number indicates the orientation of the orbital in space.
Why is the 2s subshell of heigher energy than the 1s subshell?
The 2s subshell has a higher energy level than the 1s subshell due to the presence of more nodes in the 2s orbital, which increases its energy. Additionally, the 2s orbital has a larger principal quantum number (n) than the 1s orbital, leading to greater distance from the nucleus and therefore higher energy.
What is the second quantum number of a 2s2 electron in phosphorus 1s22s22p63s23p3?
ml=0
What is the mathematical expression for the wave function of a 2s orbital in quantum mechanics?
The mathematical expression for the wave function of a 2s orbital in quantum mechanics is (2s) (1/(42)) (Z/a)(3/2) (2 - Zr/a) e(-Zr/(2a)), where represents the wave function, Z is the atomic number, a is the Bohr radius, and r is the distance from the nucleus.
The major difference between a 1s orbital and a 2s orbital is that?
the 1s orbital is closer to the nucleus and has a lower energy level compared to the 2s orbital. Additionally, the 2s orbital has a slightly higher energy, larger size, and can hold more electrons than the 1s orbital.
How a 1s orbital different from a 2s orbital in terms of size?
The 2s orbital is larger than the 1s orbital and is higher in energy.
What is the third quantum number of a 2s2 electron in phosphorus 1s22s22p63s23p3?
mi=0
The 3s orbital differs from 2s orbital in that it is?
The 2s orbital and 3s orbital both have the same spherical shape and can hold a maximum of two electrons of opposite spin. They only differ because the 3s orbital is further out from the nucleus than the 2s orbital, thus the 3s orbital has a higher energy value.
What is the third quantum number of a 2s2 electron in phosphorus?
mi=0
What is the difference between a 2s orbital and a 3s orbital?
The main difference between a 2s orbital and a 3s orbital is their energy levels. A 3s orbital is at a higher energy level than a 2s orbital. Additionally, the 3s orbital has a larger size and higher probability of finding an electron farther from the nucleus compared to a 2s orbital.
