Chemistry Periodic Trends in Atomic Radii Graphing Exercise 11-15-12
*Yo Whazzup Homie Chemists? (pretty lame huh?) I am gone on the 15th and 16th of
November (Thursday and Friday). Here is the assignment you will be working on while I
am gone. It’s due by the end of the hour on Friday. You will be able to use it on
Monday’s quiz so it’s very important that you get it done and do it correctly. Carefully
read these instructions. Everything you need to complete this assignment is below I
promise. There are a ton of points to graph so you need to work efficiently to get done by
the end of the hour on Friday. Good luck and……I love you guys!! 
READ THE FOLLOWING INSTRUCTIONS BEFORE YOU START THIS
ASSIGNMENT!!!!!
**Turn to page 175 in your book and look at the quick lab at the top of the page. You
will be using Create a Graph to construct 3 graphs. You will need the periodic table you
have in your SIS as well. Here is what you will include in this assignment……
1. Construct a graph comparing the atomic radii of atoms (book page 175) with their
atomic number (on your periodic table). Yes use ALL the elements on page 175.
2. Construct a graph comparing the ionic radii (book page 175) of atoms with their
atomic number(on your periodic table). Yes use ALL the elements on page 175.
3. Construct a graph comparing the electronegativity of atoms (book page 177) with
their atomic number (on your periodic table). Yes use ALL the elements on page
177.
**See the sample graph at the top right of page 175. Use the same x axis for each graph.
YOU WILL HAVE TO CHANGE THE Y AXIS FOR EACH GRAPH!! Then look at
the sample gray box of lithium on the right of the page to find the location of the atomic
and ionic radii you will use. The electronegativities are located on page 177. Once you
have constructed the graphs answer the questions below and submit your work to
Moodle. Make sure to include all 3 graphs right here in this document.

Explain what is meant by the atomic radius of an atom.
Explain what is meant by the ionic radius of an atom.
Explain what is meant by the electronegativity of an atom.
Describe how the size of the atomic radii changes when an atom forms a cation
(positive ion formed from losing an electron)
Describe how the size of the atomic radii changes when an atom forms an anion
(negative ion formed from gaining an electron).
Describe how the size of the ionic radii vary within a group of metals.
How do the ionic radii vary within a group of non-metals?
Is the trend across a period similar or different for periods 2, 3, 4 and 5? Explain
