Question

Number of electron in chromium for orbital angular momentum quantum

Answer 1

1s2 2s2 2p6 3s2 3p6 4s1 is the electronic configuration of the 19th electron of chromium. note:+1/2 or -1/2 are used to distinguish between electrons as no two electrons can have the same electronic configuration, but here the question isn't that specific, so we need not bother
