7) (10 pts Circle the following statement(s) that are true. a) The 25 electron has a circular orbit around the nucleus. b) An electron in a 2p, state is always closer to the r-axis than an electron in a 2s state. e) The energy of an electron in a 3s state is negative. 8) (10 pts) Write down the number of significant figures in the following two values: a) 0.0040580 g b) 4.05800 x 107 g 9) (10 pts) Write down the (ground state) electronic configurations (1s2...) of oxygen O. Note: Do not write down the orbital diagram that involves half arrows. Instead, start with 1s?. a 10) (10 pts) One of the orbital diagrams for the hydrogen atom (ground state) is in a similar way, write down one of the orbital diagrams for fluorine F (ground state). (Use half arrows instead of full arrows, even though a full arrow was used in the example above.) 11) (10 pts) Write down the number of valence electrons in the following: a) I and b) P. Note that I and I have a different number of valence electrons. Do not write the Lewis dot structures, just give a number for each one.)
