Answers
Explanation:
make me brainly brilliant
The four quantum numbers for 1s¹ electron are:
n = 1, l = 0, m= , m = 0, and s = +1/2 / -1/2.
- In atomic chemistry, there are four types of quantum numbers.
- These four quantum numbers are
- Principal quantum number- It is denoted as "n".
It tells about the shell in which the electron is revolving.
2. Azimuthal quantum number- It is denoted as "l".
It tells about the orbital of the revolving electron and its shape.
Its value is 0 to n-1.
For l = 0 for s subshell
l = 1 for p subshell
l = 2 for d subshell
l = 3 for f subshell
3. Magnetic quantum number - It is denoted as "m"
It tells about the orientation of the electrons.
Its value is -l...-1, 0, 1, +l.
4. Spin quantum number- It is denoted as "s".
It tells about the angular momentum of the electron.
Its value is +1/2 and -1/2.
- Therefore for 1s¹ electron has
n = 1
l = 0
m = 0
s = +1/2 or -1/2
