The atomic number of an atom is determined by the number of ___________ in its nucleus.

How fast do plates move relative to one another?

Which real-world geographical location is a prime example of an oceanic-continental collision?

I have the required items needed for this course: a computer with microphone, web camera (this has to be separate so you can do a side-angle view), and reliable internet (OR I can go to campus and use campus computers every week, multiple days per week AND for any exams that are online) a non-graphing calculator paper, pens/pencils etc a notebook for lab

I understand that the lecture content of this course is online, in the format of video links.  Watching and taking notes on all lecture videos is required in this course.

In this chart, a periodic property is graphed for the first 35 elements on the periodic table. The first element of each row (Li, Na, and K) are indicated with squares and labeled on the graph. Identify patterns in the way this property changes along the first three rows.    Image Description Graph starts at 0 increases to about 1/2 for Li (the first element in row two). It continues to increase for the next two elements, levels off, then drops to 0 for the final 4 elements of the row. Na (the first element in row three) is at 1, increases for the next two elements, levels off, and drops to 0 for the last two elements. K (the first element in row four) is at about 1. Increases for the next eight elements, levels off, decreases for 6 elements, drops to 0 for the final element in the row Use the information in the chart to predict which of Rb, Pd, and Xe (atomic numbers of 37, 46, and 54) have the largest and smallest values of this property, then place them in order from smallest to largest (smallest first, biggest last).

This diagram depicts the energies of a few shells (energy levels) for the atom that produced the spectrum above. Image Description Diagram of five lines to represent energy levels drawn horizontally. N=1 is at the bottom and n=5 is at the top. Starting from the top, the line n=5 is shown. Moving downward, there is a small gap between the lines n=5 and n=4, a slightly larger gap between n=4 and n=3, an even larger gap between n=3 and n=2, and a very large gap is shown between n=2 and n=1. Which of the following situations would cause the atom to emit the highest frequency photon?

Which browser is required to use Honorlock for your exam?

What is the distance between two successive light areas called? The distance is labeled 1 on the picture.

Louis de Broglie proposed that all matter has a dual nature. The wavelength of any particle is related to its momentum by this equation: Which of these is the best explanation of why we don’t notice wave behavior in large objects like baseballs, but it is fairly easily detected in small objects like electrons?
