Please fill in correct answers in table at the end of the document No other Total time allowed- 1 hour The distance between two adjacent peaks of a wave is known as th frequency wave amplitude wavelength velocity none of these Which of the following colors of visible light has the longest wave length? green orange red yellow blue What is the wavelength of light with a frequency of 8.2 Times 10^13 s^-1? 2.8 Times 10^-5 m 7.2 Times 10^-7 m 4.8 Times 10^-7 m 3.7 Times 10^-6 m none of these The energy of the electron in the hydrogen atom depends on the quantum number(s) n only n ans l l and m l only n, l and m The quantum number l for an electron in an atom is 2. This electron is definitely located in the first principal cell the second principal cell an s subshell a p subshell a d subshell From the restrictions on the three quantum numbers that define an orbital, which set of three numbers listed below is forbidden? n = 4, l = 3, m = -2 n = 4, l = 2, m = -2 n = 4, l = 3, m = 3 n = 4, l = 4, m = -2 n = 4, l = 1, m = 1 How many possible orientations are allowed when l = 1? (p-type sublevel; How many possible values are possible?) 1 2 3 5 7 Which full set of four quantum numbers would be expected for the highest energy electron for a potassium atom? n = 4, l = 0, m_i = 0, m_s = +1/2 n = 4, l = 1, m_i = 1, m_s = +1/2 n = 4, l = 2, m_i = 2, m_s = +1/2 n = 3, l = 1, m_i = 1, m_s = +1/2 n = 3, l = 2, m_i = 2, m_s = + 1/2

Explanation / Answer

5.

if l = 2, this means that 0,1,2 = s,p,d; it is in the "d" subshell

6.

d, since l = n-1, and l = 4 and n = 4, therefore this is impossible

7.

orientation --> l = 1, then

ml = 0,-1,+1 = 3 orientations

8.

highest energy electron

must be in the highest level

n = 4

and the highest subshell possible, that is, 2

choose C
