Answers
Answer:
atomic number of nitrogen =7
electronic configuration of nitrogen=2, 5
N=1s2, 2s2, 2p1
Answer:
The set of quantum numbers of the 5th Nitrogen atom is n = 2, l = 1 m = -1, and s = +1/2.
Explanation:
Given,
The element Nitrogen whose atomic number is 7.
To find,
The set of quantum numbers for the 5th electron in the Nitrogen atom.
Calculation,
The electronic configuration for the Nitrogen atom is:
1s² 2s² 2p³
The 5th electron in the nitrogen atom will be in the first subshell of shell 2p.
The Principle quantum number (n) = 2 (As the 5th electron is in the second shell ).
The Azimuthal quantum number (l) = 1 (As l = (n - 1), so l = (2 - 1) = 1).
The magnetic quantum number (m) = -1 (As m has the range from -l to +l, and the electron is residing in the first subshell of shell 2p, where l = azimuthal quantum number).
The spin quantum number (s) = +1/2 (As s can be +1/2 or -1/2).
Therefore, the set of quantum numbers of the 5th Nitrogen atom is n = 2, l = 1 m = -1, and s = +1/2.
