Periodic Table Basics

Knowing Atomic Structure Name the 3 particles that make up an atom. What are the charges of each particle? Where would you find each particle?

What is the periodic table? A chart of the elements arranged into rows and columns according to their physical and chemical properties. It can be used to determine the relationships among the elements.

Reading the Periodic Table Periods – go across Groups – go down

How do you read the periodic table? Mass Mas

What is the atomic number? The number of protons found in the nucleus of an atom Or The number of electrons surrounding the nucleus of an atom.

What is the chemical symbol? An abbreviation of the element name.

What is the atomic mass? The number of protons and neutrons in the nucleus of an atom.

What is the atomic number? What is the atomic mass? How many protons? How many electrons? How many neutrons?

What is the atomic number? What is the atomic mass? How many protons? How many electrons? How many neutrons?

Look at Your Periodic Table in Your Book

Think Pair Share - Write How can you differentiate between periods and groups?

Think Pair Share - Write How can you differentiate between periods and groups? Answer: Periods go across and groups go down.

Think Pair Share - Write How are elements grouped on the periodic table?

Think Pair Share - Write How are elements grouped on the periodic table? Answer: Elements are grouped according to their similarities.

Think Pair Share - Write What happens to the atomic number as you move across or down the periodic table?

Think Pair Share - Write What happens to the atomic number as you move across or down the periodic table? Answer: The atomic number increases as you move across and down the periodic table.

Think Pair Share - Write What happens to the atomic mass as you move across or down the periodic table?

Think Pair Share - Write What happens to the atomic mass as you move across or down the periodic table? Answer: The atomic mass increases as you move across or down the periodic table.

Think Pair Share - Write How do you know the number of valence electrons for each element?

Think Pair Share - Write How do you know the number of valence electrons for each element? Answer: The number of valence electrons is determined by the group number.

Learning Scale Level 4 – Investigate and describe the compounds formed by bonding elements. Level 3 – Describe how elements combine to form compounds. Describe the motion of the particles in a solid, liquid, and gas. Level 2 – Use the periodic table to identify the number of protons, neutrons, or electrons in an element. Level 1 – Locate and identify elements on the periodic table.

Coloring the Periodic Table As we move through the groups on the periodic table, Color code it on your copy. Write the information in the chart.

ALKALI METALS Group 1 Hydrogen is not a member, it is a non-metal 1 electron in the outer shell Soft and silvery metals Very reactive, esp. with water Conduct electricity Image: http://www.learner.org/interactives/periodic/groups2.html

ALKALINE EARTH METALS Group 2 2 electrons in the outer shell White and malleable Reactive, but less than Alkali metals Conduct electricity

TRANSITION METALS Good conductors of heat and electricity. Groups in the middle Good conductors of heat and electricity. The transition metals are able to put up to 32 electrons in their second to last shell. Can bond with many elements in a variety of shapes.

Noble Gases Group 18 Exist as gases Non-metals 8 electrons in the outer shell = Full Helium (He) has only 2 electrons in the outer shell = Full Not reactive with other elements

Rare Earth Metals Located at the Bottom Some are Radioactive The rare earths are silver, silvery-white, or gray metals. Conduct electricity

Think Pair Share - Write What happens to the reactivity of the elements as you move from left to right across the periodic table?

Think Pair Share - Write What happens to the reactivity of the elements as you move from left to right across the periodic table? Answer: The reactivity of the elements decreases as you move from left to right.

Think Pair Share - Write Which group wants nothing to do with the other elements? Why?

Think Pair Share - Write Which group wants nothing to do with the other elements? Why? Answer: The Noble Gases will not bond with other elements because they already have a full outer energy level (8 valence electrons).

Metals, Nonmetals, & Metalloids Conduct electricity Shiny Makes up ¾ of the periodic table

Metals, Nonmetals, & Metalloids does not conduct electricity found on the right side of the periodic table
