Notes Tennessee SPI Objective: Use the periodic table to determine the properties of an element. Science Check for Understanding Identify the atomic number, atomic mass, number of protons, neutrons, and electrons in atoms using the periodic table. SPI Periodic Table Instructions 1) First click on "View" from the top-menu bar. 2) Then click on "Slide Show" from the drop-down menu. 3) Then use the right-arrow button on your keyboard to advance through this presentation. Essential Question How do I interpret periodic table information to determine the atomic number, the atomic mass, and the number of sub-atomic particles in an atom?

 We use a chart to organize elements called… The Periodic Table  Currently scientists believe there are only 98 naturally occurring elements in the universe (Reference link: Chemistry WebsiteChemistry Website  We have also created 20 man-made elements for a total of 118

Notes SPI Periodic Table Periodic table  Is a chart of all known chemical elements  Displays the different types of atoms (called elements ) Purpose  Is a tool used to quickly locate a variety of information about a particular element How is it organized  Organized into rows called periods  Organized into columns called groups (also called families)  Arranged in numerical order by the atomic number  Also arranged other ways (metals, nonmetals, metalloids, etc) Science

Hydrogen 1 H 1.0. Info in each square Atomic number  is the number of protons!  also matches the number of electrons! Chemical symbol Element name Atomic mass  Is the average mass of a sample of hydrogen atoms Notes Science SPI Periodic Table

Lithium 3 Li How to determine the number of neutrons Two Simple Steps: Notes SPI Periodic Table Science Atomic Number Atomic Mass 1) Round the atomic mass to the nearest whole number Example: rounds to 7 2) Subtract the atomic number from this rounded number Reminder: Atomic is 3 Example: = 4 neutrons

. Answer these questions on your paper Review SPI Periodic Table Science (5) What is atomic mass? (1) What are elements? Elements are the different types of atoms (2) What are the rows and columns called? Rows are periods & columns are groups or families (3) Describe 3 ways the periodic table is organized. …organized in rows (periods) according to the atomic number. …organized in columns (families) according to similarities …organized into metals, nonmetals, and metalloids (4) What is an atomic number? It is the number of protons in an atom It is the average mass of a sample of the same kind of atoms
