Question

Write the
quantum numbers for the given conditions
a. 5th electron of
carbon
b. 10th electron of
Neon
c. 21st electron of
scandium
​​

Answer 1

Answer:

A common question about quantum numbers might ask, “What is the highest energy electron for the element scandium, Sc?” To answer this question you would find the last electron needed for Sc, which is electron 21, and then use it's quantum numbers: {3,2,-2,1⁄2}.

Answer 2

Answer:

i.e. +12 So the values of the sixth electron's quantum numbers are-2,1, - 1,+12 . Hence the correct answer is option D. -The principal quantum number 'n' tells about the number of the principal shell in which the electron is present.
