Cards in this deck (25)
- 1What is the definition of Frequency?the number of waves that pass a given point per second
- 2What is the definition of wavelength?the distance between equivalent points on a continuous wave
- 3What is the definition of quantum?the minimum amount of energy that can be gained or lost by an atom
- 4What is the definition of the ground state?the lowest allowable energy state of an atom
- 5What is the definition of atomic orbital?The 3-dimensional region around the nucleus, describing electrons probable location
- 6What is the definition of valence electrons?electrons in the atoms outermost orbitals
- 7Arrange the following types of electromagnetic radiation in order of increasing wavelength? a: ultraviolet light b: microwaves c: radio waves d: x raysx rays, UV, Microwaves, radio waves
- 8What is the photoelectric effect?when metal emits electrons when light of sufficient frequency
- 9How does light emitted from a neon sign differ from sunlight?neon sign contains certain visible colors or specific bands on an emission spectrum: sunlight: contains all colors, continuous spectrum without bands
- 10What are two differences between the red and green electromagnetic waves in a rainbow?red and green have different wavelength and frequency
- 11According to the Bohr model, how do electrons move in atoms?electrons move in circular planetary like orbits
- 12What does n designate in Bohr's atomic model?is principle quantum number, electron’s orbit, energy level or shell
- 13What is the definition of an excited state?energy state higher than ground state and is unstable
- 14What is the maximum number of electrons an orbital can contain?2
- 15How does the quantum mechanical model of the atom describe the paths of an atom's electrons?gives no description of electron paths
- 16Why is it impossible to know precisely the velocity and position of an electron at the same time?photons required to measure electron’s velocity would change electron’s position & vice versa; Heisenberg Uncertainty Principle
- 17Light is said to have a dual wave particle nature. What does this statement mean?light exhibits wavelike behavior in some situations and particle like behavior in others double slit experiment
- 18When writingAufbau Principle, Pauli Exclusion Principle, Hund’s Rule
- 19How many orientations are possible for the orbitals related to s sublevel?1
- 20What are the shapes of the s orbital?sphere
- 21How many orientations are possible for the orbitals related to p orbital?3
- 22How many orientations are possible for the orbitals related to d orbital?5
- 23How many orientations are possible for the orbitals related to f orbital?7
- 24What are the shapes of the p orbital?dumbbell
- 25What are the shapes of the d orbital?clover shape or 2 perpendicular dumbbells
