Which of the following statements is TRUE? The angular momentum quantum number (1) describes the orientation of the orbital. The magnetic quantum number (mi) describes the size and energy associated with an orbital. The principal quantum number (n) describes the shape of an orbital. O An orbital is the path that an electron follows during its movement in an atom. The spin quantum number (ms) describes the orientation of the spin of the electron.

Which of the following statements is true? a) The principal quantum number, n, describes the shape of an orbital. b) An orbital is the path an electron follows during its movement in an atom. c) All orbitals in the same atom are roughly the same size. d) Atoms are roughly spherical because when all the different shaped orbitals are overlapped, they take on a spherical shape. e) All of the above are true

5. A wave function for an electron in an atom is called an atomic orbital; this atomic orbital describes a region of space in which there is a high probability of finding the electron. Energy changes within an atom are the result of an electron changing from a wave pattern with one energy to a wave pattern with a different energy (usually accompanied by the absorption or emission of a photon of light). Each electron in an atom is described...

According to Graham's Law of Effusion, gases that have low molar masses have higher speeds than gases with high molar masses. B. Boyle's Law states that pressure is directly proportional to volume. C. Kinetic Molecular Theory states that the size of a gas particle is significant in comparison to its volume. D. Gases will deviate from ideal behavior if pressure is very low. E. An endothermic...

0/4 pts Question 5 Electrons exist in orbitals within an atom. Bohr's model described a single electron system well. But the energy level for orbitals change when as you add a second and more electron. In a single electron system, there are (a)_orbital(s) at the n-2 level. These n-2 orbital(s) exist at (b) sub-level(s) in the atom. In a multi-electron system, (c)_orbital(s) at the n-2 level. These n-2 orbital(s) exist at (d)sub-level(s) in the atom. Bohr was never...

QUESTION 8 5 points Save Answer Which of the following statements is incorrect? The Pauli exclusion principle states that each electron in an atom must have its own unique set of quantum numbers. From Heisenberg's principle, we can determine accurately both the position and velocity of an atomic particle. deBroglie postulated that a beam of electrons should exhibit wavelike properties. Bohr set down two postulates. One describes the energy levels of an electron and the other describes the energy of...

Select the statement that is true about quantum mechanics concepts. Question 1 options: A An electron is free to choose any conceivable orbit around a hydrogen nucleus. B Although light is a wave, it also has particle properties. C Ultraviolet light is less energetic than visible light and interacts with molecules by causing bonds to vibrate. D When an electron falls from a high energy orbital around an atom to a low energy orbital, energy is absorbed.
