What is the value of quantum numbers (n, l, ml, ms) of 2p^3?

Explanation:

First digit of the 2p^3  gives you value of n,  in this case its = 2, So, n= 2

Second alphabet gives you the value of l,

l=0 =s

l=1 =p

l=3=d

l=4=f

since  "p" is the alphabet  in 2p^3, so in your case lt shoudlbe = 1 right?

ml= -l to +l , that is -1, 0, +1

Ms= +1/2  or -1/2 alaways remains same foe evrything.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
