##0##
of Calcium ##”Ca”## is 20.
We know that there are four which can be assigned to “describe” any electron in an atom. Each electron has a unique set of these four quantum numbers.
##n =## principal quantum number, which defines the energy level of the electron.
##l =## azimuthal (angular) quantum number defining the energy sub-level. Its values range from ##0 ” to ” (n-1)##; ##0=s, 1=p, 2=d, 3=f##
##m(l) =## magnetic quantum number indicating orbital within a sublevel. Range from ##-l” through “##0##” to “+l##
##m(s) =## spin quantum number. It identifies an electron within an orbital and can have either of the two values ##+1/2 and -1/2##
================================
The electronic configuration of calcium is:
##1″s”^2; 2″s”^2, 2″p”^6; 3″s”^2, 3″p”^6; 4″s”^2## or ##[“Ar”] 4″s”^2##
it is evident that the ##19th## electron goes to ##4″s”## energy level.
As such for it ##n=4, l=0##
We know that for ##l=0, m(l)=0## only.
Hence magnetic quantum number ##m(l)## of ##19th## electron of calcium is ##=0##
