Comparing Atoms
What is an element?
a. How many elements are represented on the periodic table supplied with the game?
b. What makes each element unique? For example, how is hydrogen different from oxygen?
What holds an atom together?
a. The north and south ends of a magnet are like charges. Your teacher has given you two magnets to
work with. How are these two magnets like protons and electrons?
b. Why do you think atoms with large atomic numbers (greater than 83) do not have stable isotopes?
Introduction to the Atomic Challenge
a. What do you know about an atom if you know its atomic number?
b. What do you know about an atom if you know its mass number?
c. A fluorine atom has 9 protons and 10 electrons. It has a total charge of negative one (-1). What do
you call this charged atom?
d. What would you need to do to make this atom neutral?
e. How many stable isotopes does oxygen have?
f. Name one element that has no stable isotopes.
