A portion of the periodic table is shown below. Which column of elements would be most likely to chemically combine with potassium in a 1:1 ratio?
Nitrogen, Phosphorus, Arsenic group
Oxygen, Sulfur, Selenium group
None of these groups would combine with potassium in a 1:1 ratio

Select the best statement to describe the phenomenon of light emission from an excited hydrogen atom. (There may be more than one correct statement, but choose the "fullest" correct statement)
When electrons absorb energy, they release light of varying wavelengths, depending upon which energy shell they are going to.
As the electrons absorb energy, they release light.
When the electrons return to ground state, they release light of varying wavelengths, depending upon which energy shell they are returning from.
When electrons release light from an excited hydrogen atom, it can be of any wavelength, even more than the four shown in the model.

The image shows Force of Attraction values for four scenarios. Select the best description of the trend shown.
The force of attraction increases as the number of protons decreases
The force of attraction increases as the distance increases
The force of attraction increases as the number of protons increases.
The force of attraction decreases as the number of protons increases
Which statement best describes the relationship between distance and force of attraction.
As the distance between the oppositely charged particles increases, the force of attraction increases.
As the distance between the oppositely charged particles increases, the force of attraction decreases.
As the number of positive particles increases, the force of attraction decreases.
The shorter the distance between oppositely charged particles, the weaker the force of attraction is.
