Welcome to Unit 2! Check Schoology for new due dates! All work done by the end of MP1 (10/31)!
Other Content Videos
Other Content Videos
These videos are NOT required, but do offer a different perspective on the topic if that helps!
Crash Course - historical and scientific discussion of the periodic table
Professor Dave - a quick overview of the three trends with a little background information on the periodic table as well.
The Science Classroom - detailed discussion of the AR trend and why it exists
sciencepost - detailed discussion of the EN trend and why it exists
Ali Hayek - more technical discussion of the IE trend
FUS Chemistry Videos - A chemical demonstration of the trend in chemical reactivity with some explosive metals.
Written Content
Written Content
Open the menu below for typed content, like in a textbook. Some prefer to learn from reading rather than watching. If that helps you these resources can be useful!
AACT - An interactive that compares the atomic radii of different atoms to illustrate the trend.
LibreTexts - A thorough run through of the individual trends with brief explanations of each.
SparkNotes - Focuses on the explanation of why each trend occurs. Very concise.
Resources
Atomic Radius Plot - This is the plotted data for atomic radius vs. atomic number used to ID the trend in atomic radius. You need to make a version of this ON YOUR OWN (Lab activity) but this is here just in case!
Electronegativity Plot - This is the plotted data for electronegativity vs. atomic number used to ID the trend in electronegativity.
Ionization Energy Plot - This is the plotted data for ionization energy vs. atomic number used to ID the trend in ionization energy.
On the back of your periodic table is a summary of the trends, or patterns in data, for the properties discussed in the video: ionization energy, electronegativity, and atomic radius.
Use this information to place the atoms in the linked practice above in order.
The trends on the back of your periodic table will tell you how that property changes as you move around on the periodic table. Use this to place the atoms in your question into either increasing or decreasing order, based on their locations on the periodic table.
In this lab activity we will be plotting data about atomic radius, electronegativity, and ionization energy to help ID the patters in the data that we can match up to the periodic table. The results of these plots will be the trends that we use to predict the properties of elements based on their location on the periodic table.
In groups of 1-2 people, create a shared spreadsheet online and follow the instruction in the linked doc to create the 3 plots. We will discuss the meaning of these plots in class over the next week.
Mastery Quiz
Mastery Quiz
To prove mastery of this topic you will need to take a quiz on Schoology. Here are the guidelines:
You must show me all the completed work for this section BEFORE you you can start attempts on this quiz.
You can use any notes, practice, or prior quiz attempts to help you complete the quiz.
You can use ANY class resources like a calculator, your periodic table, or any other reference materials
You have UNLIMITED attempts to take this quiz, but after 4 tries you will need to take a paper version with me in class.
You should only need 2-3 tries for each quiz. If it takes more than that you should be reaching out for help!
You CANNOT work with others on the quizzes
