3. Define atomic number and mass number.
Back to Jeopardy Game Board

4. Mass number: the number of protons and neutrons in an atom’s nucleus.
Atomic number: Number of protons in the nucleus of any atom of that element. For example, copper has an atomic number of 29 so therefore it has 29 protons.
Mass number: the number of protons and neutrons in an atom’s nucleus.

Isotope- two or more atoms of the same element that have the same # of protons but a different # of neutrons. Example: one atom of carbon has 6p+ and 6 neutrons. Another has 6p+ and 7 neutrons.
Ion – a charged atom (unequal #p and #e)

How many electron orbits would you expect to find in a neutral atom of aluminum (atomic number 13, atomic mass )? Explain your reasoning.
Back to Jeopardy Game Board

12. Daily Double!!! Back to Jeopardy Game Board
An Aluminum atom has an atomic number of 13, therefore it also has 13 electrons.
We know that the electron orbits have the following capacities:
1st shell: 2 electrons
2nd shell: 8 electrons
3rd shell: 8 electrons
We can then conclude that aluminum will completely fill its 1st shell (2 electrons) and its 2nd shell (8 electrons). Since aluminum has filled 2 shells, with 10 electrons (8 +2), 3 electrons remain (13-10 =3). Therefore 3 electrons will be placed in the 3rd shell.
After completing the above information, we can conclude that aluminum will have 3 electron orbits

True or False
The periodic table can often be found and arranged in many different ways. Simply, many periodic tables do not look the same. Why are there different versions of the periodic table, and is it okay that they are not identical?
Back to Jeopardy Game Board

22. Back to Jeopardy Game Board
Yes, it is okay that they are not identical. Most periodic tables provide a legend that allow for an easy understanding of the periodic table. LIKE A MAP. The periodic table has developed and improved throughout time, and as more information has been discovered, more information has been added. Even though many periodic tables don’t look identical, they still contain the important information that would be needed to answer any questions.
