SPI 0807.9.9 Periodic Table Notes Science Tennessee SPI Objective: Use the periodic table to determine the properties of an element. Check for Understanding Identify the atomic number, atomic mass, number of protons, neutrons, and electrons in atoms using the periodic table. Essential Question How do I use the periodic table to determine the atomic number, the atomic mass, the number of sub-atomic particles, & other properties in an atom?

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

Notes Science Periodic table SPI 0807.9.9 Periodic Table Purpose 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)

H 1 Hydrogen 1.0 Notes Science Info in each square SPI 0807.9.9 Periodic Table Notes Science . 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 Hydrogen 1 H 1.0

How to determine the number of neutrons SPI 0807.9.9 Periodic Table Notes Science . How to determine the number of neutrons Lithium 3 Li 6.941 Two Simple Steps: Atomic Number 1) Round the atomic mass to the nearest whole number Example: 6.941 rounds to 7 2) Subtract the atomic number from this rounded number Reminder: Atomic number is 3 Example: 7 - 3 = 4 neutrons Atomic Mass
