Questions
column I | column II | ||
(a) | No. of electrons in Na (11) having m = 0 | (p) | 7 |
(b) | No. of electrons in S (16) having | (q) | 15 |
(c) | No. of maximum possible electrons having spin in | (r) | 8 |
(s) | 12 |
detailed solution
Correct option is A
2 from 1s, 2 from 2s, 2 from 2p, and 1 from 3s add up to 7 electrons when m = 0 in the sodium atom.
Now we have,
Here for and electrons which is for 8 electrons.
The transition metal chromium has an atomic number of 24. No. of maximum possible electrons When the value of s is positive 1/2, it equals 15 in.
