How many electrons are there in the valence quantum level of copper(Atomic, number = 29)?
Arrange the following orbitals in order of increasing energy:3s, 2p, 4d, 3p, 5s
The atomic number of a certain element is 17. Determine the number of electrons in each shell of the atom.
Thus:
(i) K shell has 2 electrons.
(ii) L shell has 8 electrons.
(iii) M shell has 7 electrons.
What are n, l and m value for 2px and 3pz electrons?
(i) For 2px1 electron:
n-2, l= 1, m =-1
(ii) For 3pz electron:
n = 3, l= 1, m = + l
