Unformatted text preview: this series continues on to g,h,i, etc. orbitals. Atoms that have been discovered or made up to this point in time only have electrons in s, p, d, or f orbitals in their ground state configurations. Quantum Numbers ms • The last quantum number is the spin quantum number, ms. • The spin quantum number only has two possible values. ms = +1/2 or -1/2 • This quantum number tells us the spin and orientation of the magnetic field of the electrons. • Wolfgang Pauli in 1925 discovered the Exclusion Principle. – No two electrons in an atom can have the same set of 4 quantum numbers. 7 1/21/2014 • Remember: – SHELL – corresponds to n level – SUBSHELL – corresponds to the l level – ORBITAL – corresponds to the specific ml Principal quantum n 1 ‘K’ SHELL l Magnetic quantum 0 ml 0 Azimuthal quantum ‘s’ SUBSHELL 1s ORBITAL How many e- can be assigned in an orbital? Ans: 2 electrons only, one is spin up (ms = +1/2), the other is spin down (ms = -1/2) Atomic Orbitals • Atomic orbitals are regions of space where the probability of finding an electron about an atom is highest. • s orbital prop...
