Atomic Structure
What are the three main subatomic particles that make up an atom?
What are protons, neutrons, and electrons
What is an isotope?
What are atoms of the same element with different numbers of neutrons?
In the Bohr model, where are electrons located?
What are in specific energy levels around the nucleus.
What does the electron cloud model describe?
What is the regions around the nucleus where electrons are likely to be found?
What is the charge of a proton?
What is positive
How do the isotopes of an element differ?
What is they have a different mass number
What happens to an electron when is absorbs energy in the Bohr model?
What is, it moves to a higher energy level.
How does the electron cloud model differ from the Bohr model?
What is it does not define specific paths for electrons, but rather probabilities of where they may be?
Where is most of an atom's mass located?
What is the nucleus
Give an example of an isotope of oxygen
What is oxygen- 18
Describe a limitation of the Bohr model
It cannot accurately predict the behavior of multi-electron atoms.
How are electron clouds visualized?
Define atomic number
What is the number of protons in an element
How is the average atomic mass of an element calculated?
What is by taking the weighted average of the masses of its isotopes.
What does the Bohr model explain about the emission of light from atoms?
How are orbitals related to the electron cloud model?
Orbitals are specific regions within the electron cloud where an electron is most likely to be found.
How do you determine the number of neutrons in an atom?
What is mass number - atomic number
Why are some isotopes radioactive?
What is because they have unstable nuclei
Who developed the Bohr model of the atom?
Who is Niels Bohr?
Which scientist is most associated with the development of the electron cloud model?
Who is Erwin Schrodinger
