Question
ors, p, and d orbitals (in that order) in an atom's n=3stel is b. 1, 2. 3 c. 1, 3, 4 d. 1, 3, 5 e 1, 3, 22 The name of the orbital with quantum nunters n a. 3p b. 4s 4 and-3 is the c. 4p d. 4d e 4 23. The allowed magnetic quantum numbers, m, are Integers from-to b. Integers 0, 1, 2, etc C. +1/2 and -1/2 d e. Integers from 0 to n-1 Integers from-nto +n 4. It is impossible to know simultaneously with exact precision both the precision and momentum of a small particle such as an electron is given in (the) a. Aufbau Principle b. Pauli Exclusion Principle c. Heisenberg's Uncertainty Principle d. Hund's Rule e Schrodinger Equation Which of the following statements is false? a. A heated solid emits a line spectrum, showing only certain wavelengths of light b. Einstein postulated that light consists of particles of electromagnetic energy (photons), with 25. energy proportional to the observed frequency of the light c Diffraction is a property of waves in which the waves spread out when they encounter an obstruction or small hole about the size of the wavelength. d. A wave function contains information about a particle in a given energy level, such as an e. None of the above is false Which of the following statements is false? electron in an atom 26. a. Rutherford's theory of the atom did not explain why the electron did not spiral into the nucleus Bohr's energy-level postulate stating that an atom has only specific energy levels explains why electrons don't cascade into the nucleus b. c. Bohrs postulate that an electron in an atom can change energy only by going from one energy level to another accounts for a gaseous atom's line spectra having only specific wavelengths of light Bohr's theory predicts atomic energy levels for atoms other than hydrogen. None of the above. d. e.Explanation / Answer
1. d. 1, 3, 5
for n = 3
l = 0 to (n-1)
l = 0, 1, 2 and we know that for , l = 0, s orbital, s =1
l = 1, p orbital, p = 3
l = 2 d orbital. d = 5
2. e. 4f
we know that l = 3 is only for f orbital.
3. a. integers from -l to +l
magnetic spin quantum number always use to define with the -+l including zero in it.
4. c. Heisenberg uncertainty principle
this principle only say about the uncertainty on the position and time with respect momentum and energy respectively.
