Question

What is the maximum possible electrons in a 3f subshell? 0 b. How many electrons can have the quantum numbers n = 5, l = 4, m_1 = -1 2 c. Identify the subshell represented by these quantum numbers n = 4, l = 2 4d d. What element has three valence electrons in the 6p shell Bi e. How many unpaired electrons are present in the ground state of Copper 1(one) f. Identify the element that has 4 valence electrons, one of which has this quantum number n = 3, l = 1, m_l = -1, m_s = 1/2 Si g. Name the quantum number that determines the orientation of an atomic orbital Magnetic orientation

Explanation / Answer

a) there is no 3f subshell thus 0 electrons in it.

b) n=5 ,l=1, m = -1 the orbital is a 5p orbital that can accommodate 2 electrons.

c) n=4 and l=2 the designation is 4d

d) The element with 3 valence electrons in 6p is Bi with configuration [Xe] 4f14, 5d10, 6s2 and 6p3

e) copper 29 has the outer configuration as [Ar] 3d10 4s1. Thus the number of unpaired electrons are ONe.

f) n=3, l=1, m= -1 and s= 1/2 corresponds to 3p1

this configuration with 4 valence electrons is Si

Si (14) has 1s2 2S2 2p6 3s2 3p2[ 3px1 3px1]

g) the quantum number that determines the orientation of an atomic orbital is the magnetci quantum number.
