|
Answer» Answer: 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 . |
