d. 246 kJ 3. The number of orbitals in a d subshell is a. 5 b. 3 4. The maximum number of electrons that can occupy the 3d shell is c. 18 d. 32 5. How many electrons can an orbital hold? a. noneb. 1 only c. 2 only d. either 0,1 or 2 6. Which element has the following electron configuration: 1s22s22p 3s2 a. Na b. Mg C. Al d. Ne 7. Which element has the following electron configuration: a. Na b. Cr c. Mn d. Fe 8. Transition metals have atoms or ions with partially filled a. s subshells b. p subshells c. d subshells d. f subshellsExplanation / Answer
Q3
orbitals in dsubshell
l = 0,1,2,3, --> s,p,d,f, then if l = 2, then ml = 0,1,2,-1,-2 = 5 orbitals
Q4
Tmax --< 3rd shell ---> n = 3, l = 3-1 = 2, then ml = 0,1,2,-1,-2
3s = 2
3 p = 6
3d = 10
Total e- = 10+6+2 = 18
Q5
they can hold up a max 2 electron, since +1/2 and -1/2
Q6
total e- = 2+2+6+2 = 12 , this is Mg
Q7
total e- = 2+2+6+2+6+2+5 = 25
Mn
Q8
Typically, "d" subshells
