Periodic Table Scavenger Hunt
Use the Periodic Table of the Elements to find out the following:
1. Every element has a unique atomic number that is equal to the number of protons in a single atom of
that element.
How many protons does sulfur have?
What is the symbol for sulfur?
2. What is the atomic number of helium?
What is the symbol for helium?
3. What is the atomic number of magnesium?
What is the symbol for magnesium?
4. Which of the following three elements has the most protons? Boron, chlorine, or potassium?
5. What is the symbol for lithium?
6. What element has the symbol Zn?
7. What is the symbol for gold?
8. The atomic mass of an element is a combination of the number of protons and neutrons. Because
the same element does not always have the same number of neutrons, the atomic mass is an average
mass of the element as it occurs in nature. What is the atomic mass of fluorine?
9. Which element has an atomic mass of 207.20 amu?
10. Round off the atomic mass of silicon to the nearest whole number. Subtract silicon’s atomic
number from the rounded atomic mass for the number of neutrons in a typical silicon atom.
11. How many neutrons are found in the typical phosphorus atom?
12. A neutral atom has the same number of electrons and protons. How many electrons does a neutral
atom of argon have?
13. Which neutral atom would have 4 electrons?
14. Which element has an atomic mass of 55.847 amu?
15. Write the name of the element that has a symbol matching the following state abbreviations (but
remember the second letter of an element symbol is always lowercase!)
