Are the elements of larger atoms harder to melt than those of smaller atoms?
We can investigate this type of question if we assume that bigger atoms have more protons (larger atomic number), and compare the atomic number to the properties of the elements.
Data: Properties of the First 20 Elements
Question 1.
Your job is to use the data linked above to draw a graph to show the relationship between Atomic Number of the element and the property you are assigned.
Question 2.
What is the relationship between the number of valence electrons of the elements in the data table and the property you were assigned.
Bonus Question
Bonus 1: The atomic number can be used as a proxy for the size of the element because it gives the number of protons, but it’s not a perfect proxy. What is the relationship between the atomic number and the atomic mass of the elements?
