How can you determine the number of protons, neutrons, and electrons?
Protons are the same as the Atomic Number, electrons are the same as the number of protons, and neutrons can be calculated by subtracting the number of protons from the atomic mass.

What is the number on the bottom of each tile on the periodic table?
Average atomic mass
200
What is Hund's Rule?
Every orbital in a subshell is singly occupied with one electron before any orbital is doubly occupied. All electrons in singly occupied orbitals must have the same spin.
200
What is produced when an electron goes from the excited state to the ground state?
Photons

Describe the experiment Rutherford used to develop his model and his results
Rutherford's Gold Foil Experiment involved directing alpha (He) particles at a thin sheet of gold. Most particles passed through the sheet, but some were deflected off the nucleus of the gold particles. The experiment resulted in the discovery of the nucleus.
300
What is the smallest particle of an element that retains its properties?
An atom
300
How are isotopes of the same element different, besides their subatomic particles?
They have a different mass numbers
300
Where are the valence electrons in an atom?
Valence electrons occupy the outermost shell
300
What is the relationship between wavelength, frequency, and energy?
As wavelength increases, frequency and energy decrease, and vice versa.
400
Describe how the atomic model appears in the "Plum Pudding" model.
Electrons were negatively charges species stuck in a positively charged area ("pudding").
400
Where are each of the subatomic particles located?
Protons and neutrons are in the nucleus. Electrons are outside of the nucleus.
400
If an isotope is written like 136C, what do the 13 and 6 represent?
The 13 is the mass number and the 6 is the atomic number
400
What happens to the energy when an electron move from the innermost shell to the outermost shell?
The energy increases
400
What is the visible spectrum (in decreasing wavelength)?
Red, orange, yellow, green, blue, indigo, and violet (ROY G BIV)
500
Which model was proposed using a cathode ray tube?
Thompson's plum pudding
500
What types of atomic orbitals (s, p, d, f) are in the first 4 energy levels?
1 - s; 2 - s and p; 3 - s, p, and d; and 4 - s, p, d, and f
500
How do you calculate the average atomic mass?
(Mass Number 1 x Relative Abundance 1) + (Mass Number 2 x Relative Abundance 2) + (Mass Number 3 x Relative Abundance 3)
500
What is the noble gas shorthand electron configuration for Barium (Ba)?
[Xe] 6s2
500
What are the parts of the electromagnetic spectrum (from shortest to longest wavelength)?
Gamma rays, X-rays, UV, Visible, IR, Microwave, Radiowaves (FM then AM), and Long radio waves
