TOPIC: QUANTUM, ATOMIC AND MOLECULAR PHYSICIS a) What are the electron configurations of the molecules 07,02,07 & 0ž- ? b) Determine the symbols for the electronic terms 25+'Au of the ground states of these molecules / g,u ions. Justify your choice of ground state in each case; c) For the case of 02, how do its electronic configuration and term change when a transition occurs from its ground state to its first excited state?

Answer the following. (a) Write out the electronic configuration of the ground state for fluorine (Z = 9). O 1s²2s²2p¹ O 1s²2s²2p² O 1s²2s²2p³ O1s²2s²2p4 O 1s²2s²2p5 O 1s²2s²2p6 (b) Write out the values for the set of quantum numbers n, l, m, and må for each of the electrons in fluorine. (In cases where there are more than one value, enter the positive value first. Enter positive values without a '+' sign in front of them. Include all possible values.) 1s states n = 2s states n = 2p states n= l = P یے || = m = 0m₂ = m m m m m ms m S S m ms ms S ms = ms ms || || || = || = || ||

Indicate which of the given electronic configurations are true ground state configurations for the respective atoms and which are false. (Take care! There are some exceptions to the simple rules.)

Can you help me?

Answer correctly

Only specific amounts of energy can be absorbed and emitted by an atom. (Think how this relates to Q3.1) Here's an example of an energy level diagram Energy Photon E5 (n=5) E4 (n=4) E3 (n=3) E2 (n=2) E1 (n=1) How many possible electronic transitions are possible from the ground state (E1) into any excited state? 02 O 3 O 4 05 O More than 5

For each of the statements below, indicate whether it is true or false and explain your reasoning. (1 sentence ) 1/ It takes more energy to ionize an electron from the 2s orbital than an electron from the 2p orbital in the Li2+ ion. 2/ The electron affinity of the Ne atom is larger than the electron affinity of the F atom. 3/ K* has a larger radius than Ar. 4/ For a diatomic molecule, in which the internuclear axis is the z-axis, the 3dz? orbital cannot mix with the 2px orbital. 5/ The internuclear distance of O2 increases as it takes an additional electron to become O2".

10. Consider two hydrogen atoms. The electron in the first one is in n=1 state, whereas in the second the electron is in the n=3 state. (a) which atom is in the ground state configuration? Why? (b) Which orbital has a larger radius? (c) Which electron is moving faster and why? (d) Which electron has a lower potential energy? (e) Which atom has higher ionization energy? Hint: assume that the radius of the n=3 orbital is =5 rB

1. II. II. IV. V. Which of the orbitals above would represent one of the possible 5p atomic orbitals? No work needs to be shown for this problem. || IV O v V O II

solve this
