(a) by means of a simple table, summarise the four quantum mmbers that are assigned to electrons confined in any atom. (you may ignore the spin angular momentum quantum number which always has the value s-½.) include a statement of the allowed values of each quantum number (b) in your own words, write down: (i) pauli's exclusion principle; ) hund's rule. what other principle needs to be employed in determining the electronic structure of the ground state of an aton

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
