paramagnetic A) id B) 4s C) 3 P D) 4p E) All of the above 9. Consider the element with the electron configuration [Kr]5s24d. This A) B) element is a representative element. a transition metal. C) a nonmetal. D) an actinide element E) a noble gas. 10. What is the wavelength of radiation that has a frequency of 3.4 x 101 s-1? A) 8.8 x 104 nmm B) 8.8 x 105 nm C) 8.8 x 10-13 nm D) 1.0 x 10" nnm E) 1.0 x 10-9 nm 11. Following is the electron configuration of [Ar] 3d A) Ca B) K C) Cu D) Zn E) Cr Calculate the volume occupied by 35.2 g of methane gas (CH4) at 25°C and 1.0 atm. F = 0.08206 Latrm/KImol. A) 0.0186L B) 4.5 L C) 11.2 L D) 49.2 L E) 53.7L 12.Explanation / Answer
9) [Kr]5s2 4d7 = Rhodium(Rh)
answer: B
10) c= vl
l = c/v
= (3*10^8)/(3.4*10^11)
= 8.82*10^-4 m
= 882000 nm
= 8.82*10^5 nm
answer: B. 8.82*10^5 nm
11) Cu = 29 = [Ar] 4s1 3d10
answer: C) Cu
12) volume of methane gas(V) = nRT/P
= (35.2/16)*0.0821*298/1
= 53.7 L
answer: E) 53.7 L
