What element
is this?
The periodic table is the
chemist's roadmap to the elements! You will refer to this table often to find
atomic masses and other properties. As we progress through the semester other
chemical mysteries will be revealed. Become familiar with the layout and
information available from the periodic table by answering these questions.
The atomic number listed on the periodic table gives you
infomation about each atom's protons and electrons. If you know the mass number
of an element the number of neutrons can also be determined. Use this quiz to
practice using atomic numbers.
Here is a complete periodic table to get you started:
