How comfortable do you feel with these topics?
Great! Ready to test!
Good, this review refreshed my memory. I will need to review again before the test.
More confident about one topic than the other.
I am completely lost and need help.

What isotope is shown here? (Red = protons, gray = neutrons, blue = electrons)
Beryllium-5
Beryllium-9
Boron-4
Boron-9
The questions you've answers thus far were on Isotopes.
Isotopes are atoms of the same element with different numbers of neutrons. This causes isotopes of the same atom to have different masses. Isotopes are why atoms have an 'average atomic mass'.

Good, but I will need to review a little more before the test.
Okay. I need to practice this concept much more before the test.
I am completely lost and need help.
What subatomic particle is responsible for the spectral lines seen in emission spectra diagrams?
electrons
protons
neutrons
In order to go from ground state to an excited state, an electron must
emit energy
absorb energy
wiggle
When an electron returns to ground state from an excited state, the atom will
emit energy
absorb energy
rotate
wiggle
What can a flame test distinguish?
calcium chloride and barium chloride
calcium chloride and calcium nitrate
ethanoic acid and propanoic acid
any two metals
The questions you've answers thus far were on Atomic Emission.
Atomic emission shows us that elements produce different colors of light due to the set quantity electrons moving between specific energy levels.

How many times an electron goes around the element
The path the earth takes to orbit around the sun
*Notes: Since these were the most recent topics gone over, there were the fewest questions.
The questions you've answers thus far were on Electron Configurations, Orbital Diagrams, and Bohr Models.

What do you need to be prepared for the test this week?
TIME to review in class
(Tuesday 10/4)
HELP/reteaching from Mrs. Hilt for a specific topic
Nothing. I felt confident with my answers and got most correct. I'm prepared and ready to test.
I need review time and help/reteaching.
