Periodic Table Test of Knowledge Ms. Johnson’s Sixth Grade Science Labeling Information on the Periodic Table of Elements Select the pen tool from the box on the bottom left hand corner of this page and use it to draw a line from each label to its place on the periodic table. When you are done select automatic pointer and click the bottom right arrow to check your answer. • • • • Symbol Atomic Mass Atomic Number Name Labeling Information on the Periodic Table of Elements Check your answers with this guide. How did you do? You will need to know this information for the rest of the test. So go back and review if you need to! • • • • Symbol Atomic Mass Atomic Number Name Identifying Parts of the Periodic Table Use the square below to click on the part of the periodic table that tells the atomic mass of the element. Identifying Parts of the Periodic Table Your answer is incorrect. The number eight is the atomic number for oxygen. It represents the number of protons in one atom of the element oxygen. Click the left back button to try again! Identifying Parts of the Periodic Table Your answer was incorrect. You selected the atomic symbol. Click the left back button and try again! Identifying Parts of the Periodic Table Not quite! The word you selected is the name of the element. Click the left back button and try again. Identifying Parts of the Periodic Table You got it! The number 16.00 is the atomic mass of oxygen. If you subtract the atomic number from the atomic mass, you will find the number of neutrons in one atom of oxygen! Counting Protons in an Element Look at the insert from the periodic table to your left. How many protons are in one atom of Potassium? • 19 • 20 • 39.10 HINT Counting Protons in an Element Way to go! The atomic number is the same as the number of protons in one atom of the element. You are correct. Potassium has 19 protons and 20 neutrons! Counting Protons in an Element Sorry. Twenty represents the number of neutrons in the atom, not the number of protons. Check out the hint and try again! HINT Counting Protons in an Element Sorry. The number you selected is the atomic mass for Potassium, not the atomic number. Check out the hint and try again! HINT HINT • The number of protons is equal to the atomic number. • The atomic number is located above the symbol in any square in the periodic table of elements. • Good luck! Finding the Number of Neutrons in an Atom Look at the insert from the periodic table to your right. How many neutrons are in one atom of Boron? • 5 • 7 • 10.81 HINT Finding the Number of Neutrons in an Atom Sorry. The number 5 is the atomic number for Boron. This means that Boron has 5 protons, not neutrons. Check out the hint and try again! HINT Finding the Number of Neutrons in an Atom You got it! When you subtract the atomic number (5) from the atomic mass (10.81), you get the number 6.81. When you round this number to the nearest whole number you find that Boron has 7 neutrons! Nice work! Finding the Number of Neutrons in an Atom Sorry. The number 10.81 is the atomic mass of Boron. Check out the hint and try again! HINT HINT • To find the number of neutrons in an atom you subtract the atomic number from the atomic mass and round to the nearest whole number. • Atomic Mass – Atomic Number = Neutrons • Use a sheet of paper to solve this problem • Good luck! Using the Periodic Table of Elements On a sheet of paper write down the names of the elements listed to the right. Use this link to The Periodic Table of Elements to find the symbol for each element listed on the right. Name Symbol Iron Copper Sodium Berylium Tin _____ _____ _____ _____ _____ Using the Periodic Table of Elements Did you get them all right. Remember that the symbol is sometimes an abbreviation of the Latin word. Don’t let this confuse you! Name Iron Copper Sodium Berylium Tin Symbol Fe Cu Na Be Sn Using the Periodic Table of Elements On a sheet of paper write down the atomic numbers for the elements listed to the right. Use this link to The Periodic Table of Elements to find the Name of the element that matches the atomic number to the right. Atomic # 82 16 1 36 80 Name _____ _____ _____ _____ _____ Using the Periodic Table of Elements So……How did you do? Remember that all of the elements are listed in order by atomic number. Were there any elements that you knew without using the periodic table? Atomic # 82 16 1 36 80 Name Lead Sulfur Hydrogen Krypton Mercury CONGRATULATIONS! You have completed The Periodic Table Test of Knowledge!
