14 Questions
What colour flame does copper produce in a flame test?
blue/green
What is the limitation of the Bohr theory regarding the properties of electrons?
Did not take account of the fact that electrons have the properties of waves as well as particles
What is the Heisenberg Uncertainty Principle?
Heisenberg Uncertainty Principle states it is not possible to determine the exact position and velocity of an electron at the same time.
What is the region around the nucleus where the probability of finding an electron is relatively high?
Atomic Orbital
What is the principle that governs the occupation of energy sublevels by electrons?
Aufbau Principle
What is the term for a group of atomic orbitals with the same energy?
Energy Sublevel
What is the limitation of the Bohr theory regarding the existence of orbitals?
Did not account for the existence of orbitals
What is an energy level in an atom?
A region of definite energy within an atom that electrons can occupy.
What are the two ways to energize atoms?
Supplying heat and supplying electricity.
What is a spectrum, and what is it used for?
A spectrum is a band of colors produced when light is separated into its different wavelengths, and it is used to identify a particular gas or element.
What is the difference between a continuous spectrum and an emission spectrum?
A continuous spectrum shows a full range of colors, whereas an emission spectrum shows distinct lines of certain colors.
What is the purpose of an atomic absorption spectrometer?
To measure the presence and amount of an element.
According to Niels Bohr's theory, what happens when an electron moves from a higher energy level to a lower energy level?
A definite amount of energy is emitted in the form of light.
What is the formula to calculate the difference in energy levels?
E2 - E1 = hf, where h is Planck's constant and f is the frequency of light emitted.
Learn about the electronic structure of atoms, how to energize them, and the principles of spectroscopy. Discover the different types of spectra, including continuous and emission spectra, and how they are used to identify elements.
