(a)
Interpretation:
The shell in which the valence electron for an element of period 2 resides is to be determined.
Concept Introduction:
The periodic table is used to arrange the elements on the basis of their characteristics. In the periodic table, row is called a period and column is called a group. There is a total of 18 groups and 7 periods in the periodic table.
(b)
Interpretation:
The shell in which the valence electron for an element of period 3 resides is to be determined.
Concept Introduction:
The periodic table is used to arrange the elements on the basis of their characteristics. In the periodic table, row is called a period and column is called a group. There is a total of 18 groups and 7 periods in the periodic table.
(c)
Interpretation:
The shell in which the valence electron for an element of period 4 resides is to be determined.
Concept Introduction:
The periodic table is used to arrange the elements on the basis of their characteristics. In the periodic table, row is called a period and column is called a group. There is a total of 18 groups and 7 periods in the periodic table.
(d)
Interpretation:
The shell in which the valence electron for an element of period 5 resides is to be determined.
Concept Introduction:
The periodic table is used to arrange the elements on the basis of their characteristics. In the periodic table, row is called a period and column is called a group. There is a total of 18 groups and 7 periods in the periodic table.

- I need help with the followingarrow_forwardFor Raman spectroscopy/imaging, which statement is not true regarding its disadvantages? a) Limited spatial resolution. b) Short integration time. c) A one-dimensional technique. d) Weak signal, only 1 in 108 incident photons is Raman scattered. e) Fluorescence interference.arrow_forwardUsing a cell of known pathlength b = 1.25115 x 10-3 cm, a water absorption spectrum was measured. The band at 1645 cm-1, assigned to the O-H bending, showed an absorbance, A, of 1.40. a) Assuming that water density is 1.00 g/mL, calculate the water molar concentration c (hint: M= mole/L) b) Calculate the molar absorptivity, a, of the 1645 cm-1 band c) The transmitted light, I, can be written as I= Ioexp(-xb), where x is the absorption coefficient (sometimes designated as alpha), Io is the input light, and b is the cell pathlength. Prove that x= (ln10)*x*c. (Please provide a full derivation of the equation for x from the equation for I). d) Calculate x for the 1645 cm-1 bandarrow_forward
- For CARS, which statement is not true regarding its advantages? a) Contrast signal based on vibrational characteristics, no need for fluorescent tagging. b) Stronger signals than spontaneous Raman. c) Suffers from fluorescence interference, because CARS signal is at high frequency. d) Faster, more efficient imaging for real-time analysis. e) Higher resolution than spontaneous Raman microscopy.arrow_forwardDraw the major product of the Claisen condensation reaction between two molecules of this ester.
