Answer:
a) specifies the 3-D shape of the orbital
Explanation:
To determine the region where is more probable to find the electron, it is characterized by four quantum numbers:
- Principal quantum number (n): represents the level, or shell, where the electron is. It varies from 1 to 7, and are represented by the letters K, L, M, N, O, P, and Q.
-Azimuthal quantum number (l): represents the sublevel, or subshell. Is represented by the letters s, p, d, f, g, ... And by the numbers 0, 1, 2, 3, ... Each one has a 3-D shape, the s, for example, has a spherical shape.
-Magnetic quantum number (ml): represents the orbital inside the subshell, and varies from -l to +l, passing by the 0. Each orbital can have at least 2 electrons.
-Spin quantum number (ms): represents the spin of the electron, which can be +1/2 or -1/2.
