1 Element Facts http://education.jlab.org/itselemental/ Name: _________________________ *Directions: (1) Read the information to identify the year and scientist that discovered the (118) elements of the periodic table. (2) Locate the elements on the periodic table and write the matching symbol. (3) Write the atomic #. You will be assigned to a select element for the Element Project. (4) Record the element name, symbol, number and other data information in your science spiral. (5) Place a check next to your assigned element. Use a Periodic table, Periodic table links, science textbook, and periodic table in the agenda book (pg 125) as a reference. Date: _________________ Period: ________ *Element Symbol should be written as; Always capitalize the first letter. Use lower case letter for the second and third letters. *Example 1 Who discovered the element gold, silver, copper, neon, etc...? Below is a list of all of the known elements, who they were discovered by and the year they were discovered. Some elements, such as gold, silver and iron, have been known since ancient times, so it is impossible to credit a single person for their discovery. Other elements were discovered around the same time by two or more scientists who were working independently of each other. In these cases, each scientist is listed along with the year they made their discovery. Other elements were discovered by teams of scientists working together. In cases like this, the known members of the team are listed along with a single year of discovery. Click on an element's name for the full story!
