Question

find the value of the azimuthal quantum number and magnetic quantum number of 19th electron of its atom​

Answer 1

Answer:

Explanation:

Let us write the quantum numbers

Explanation:

Calcium

Its symbol is Ca .

Its atomic number is 20 .

The electronic configuration of calcium (20) is 1s², 2s² 2p⁶,3s² 3p⁶ 4s².

Quantum numbers

They are the certain set of numbers that tells us about the complete address of a electron .

In it :

Principle quantum number ( n) -principle shell of an atom

Azimuthal quantum number ( l )- tells about the sub shell

Its value is equal to (n-1 )

If  l=0 then it signifies --> s-orbital

If L=1 then it signifies --> p orbital

If L=2 then it signifies --> d orbital

If L=3 then it signifies --> f orbital

Magnetic quantum  number ( m )-->tells the i.e the number of orbitals present so for s subshell it is 0

spin quantum number (s) tells about the spinning the  for the electron which is +1/2 or -1/2

In the above asked question we have :

The four quantum numbers for the 19th electron would be:

n=4

l=0

m=0

s = +1/2, -1/2 .
