Aim: How is the Periodic Table of the Elements arranged? The elements on the Periodic Table are arranged in order of increasing atomic number. The number of protons identifies the element. The placement or location of an element on the Periodic Table gives an indication of the physical and chemical properties of that element.

Aim: How is the Periodic Table of the Elements arranged? Do Now: Examine your periodic tables. How do you think the elements are arranged? Why?

Aim: How is the Periodic Table of the Elements arranged? Elements can be classified by their properties and located on the periodic table as metals, nonmetals, metalloids (B, Si, Ge, As, Sb, Te) and noble gases. The number of valence electrons (outermost electrons) affects the chemical properties of an element. Alkali metal

Aim: How is the Periodic Table of the Elements arranged? Periodic Table Essential Questions : How are elements classified? Describe the properties of the alkali metals. Why is valence number important in determining placement of elements on the periodic table?
