Understanding Electronegativity and Graphing Techniques

Mrs. Foy provides a tutorial on creating graphs for periodic trends using a spreadsheet. The assignment involves graphing atomic radius and ionization energy against atomic number. She explains how to highlight data, insert charts, and customize them. Additionally, she discusses electronegativity and provides guidance on answering related questions. The video emphasizes the importance of proper graph titles and inserting graphs into lab reports.

What are the two types of graphs you need to create for the assignment on periodic trends?

• Atomic number vs. atomic mass and atomic number vs. ionization energy

• Atomic number vs. ionization energy and atomic number vs. electronegativity

• Atomic number vs. atomic radius and atomic number vs. ionization energy

• Atomic number vs. atomic mass and atomic number vs. electronegativity

What is the first step in creating a graph for atomic radius using a spreadsheet?

• Highlight the element names

• Insert a chart

• Edit the chart title

• Highlight the element symbols and atomic radius column

Why is it important to edit the chart title when creating a graph?

• To match the periodic table

• To ensure clarity and avoid losing points

• To make it easier to print

• To make it look more colorful

What should you do after taking a screenshot of your chart?

• Save it as a PDF

• Insert it into your lab report

• Email it to your teacher

• Print it out

What is ionization energy?

• The energy required to add an electron to an atom

• The energy needed to combine two atoms

• The energy needed to remove a valence electron from an atom

• The energy required to split an atom

What is the third trend mentioned in the lab that does not require graph creation?

• Atomic mass

• Ionization energy

• Atomic radius

• Electronegativity

What does electronegativity measure?

• The size of an atom

• The energy needed to remove an electron

• The pull an atom has on another atom's electrons

• The mass of an atom

How can you find the element symbols when interpreting the electronegativity graph?

• By checking the spreadsheet

• By using a periodic table

• By guessing based on atomic number

• By looking at the graph's legend

What should you do if the graph of electronegativity does not show element symbols?

• Create a new graph

• Use a periodic table to find them

• Ask the teacher for a new graph

• Ignore the symbols

What is the purpose of the provided link in the lab for electronegativity?

• To watch a video tutorial

• To submit your lab report

• To view a pre-made graph of electronegativity

• To download a new spreadsheet
