Warm UP Form the picture Define in your own words element? Elements are chemically the simples substance, cannot be broken down using chemical methods

With your group Direction for activity List of possible elements to choose form Look at the materials that you have and decide on the composition. Regarding the composition of the given material how many elements can you name ? Support your answer! One person in group will write the elements into their notebook and I will call on a person to share. Copper Aluminum Iron (Fe) Hydrogen Lithium Carbon Sodium cadmium, cobalt, lead, Nickel Mercury , Argon Nitrogen Silicon Magnesium Tungsten Cobalt Oxygen Sulfur Zinc Gold Calcium

Metal rods Iorn, copper, aluminum ,brass

Brass, copper, Platinum

Elements in Batteries cadmium, cobalt, lead, lithium, and nickel Carbon 

Light bulbs Lead, Tungsten, aluminum, Argon- Nitrogen argon gas containing mercury Rare elements:  cerium, europium, lanthanum, terbium and yttrium

WOOD  

 Much wood ash contains calcium carbonate as its major component, representing 25 or even 45 percent Less than 10 percent is potash, and less than 1 percent phosphate; there are trace elements of iron, manganese, zinc, copper and some heavy metals.

Elements of life 96% of living cells are make of C, N, H, & O 98% made of C, H, N, O, P, S

What is the periodic table? It is a chart that organizes the elements by their increasing atomic numbers as well as by their physical and chemical properties.

Who made the periodic table and when was it created? A Russian chemist and inventor named Dmitri Mendeleev created the periodic table in 1869.

3) What ability did the periodic table have? The periodic table was designed to make room for and predict the existence of elements that had not yet been discovered.

Elements Atomic Number: # of protons in nucleus (which = electrons) top number Symbol: 1 to 2 letters, first letter is capital (based off Latin name) Atomic mass: mass of the atom -in amu (bottom #)

Elements are made of atoms: Atoms are made of protons, neutrons in the middle, surrounded by electrons

Amu= atomic mass unit: both protons and neutrons have a mass of 1 amu atomic mass is equal to # of protons + # neutrons - electrons have “no” mass

5) Using the diagram, draw arrows to label the parts of the element atomic number , element symbol, element name, atomic mass

atomic number , element symbol, element name, atomic mass a) In the shaded area to the right, draw the element box for the element that has an atomic mass of 107.87. b) In the shaded area to the right, draw the element box for the element that has the element symbol Pt.

Groups: up and down columns on the periodic table -aka: Families ORGANIZATION OF THE PERIODIC TABLE Groups: up and down columns on the periodic table -aka: Families Periods: side to side rows on the periodic table

ORGANIZATION OF THE PERIODIC TABLE One way to classify the elements on the periodic table is by the periods and groups to which they belong. Periods Periods are the horizontal rows on the periodic table and are number from 1-7. Elements in the same period have consecutive atomic numbers, but they differ predictably in their chemical properties. Groups Groups or families are the vertical columns on the periodic table, numbered from 1-8. Elements in the same group usually have similar properties

6)How is the periodic table arranged? The periodic table is arranged in columns and rows. 7)What is each column on the periodic table called and how many of them are there? Each column is called a GROUP and there are 18 of them. 8) What is each row on the periodic table called and how many of them are there? Each row is called a PERIOD and there are 7 of them.

One way of organizing the periodic table…. The zigzag line or the staircase separates Metals vs Nonmetals 9 -13

9) In the diagram able, identify and highlight the zigzag line 9) In the diagram able, identify and highlight the zigzag line. What is another name for the zigzag? Label it on the diagram above. Another name for the zigzag is the STAIRCASE. 
 10) Describe where the metals are found on the periodic table. Label them “metals” on the diagram . The metals are found on the LEFT side of the staircase. 
 11) Describe where the non-metals are found on the periodic table. Label them “non-metals” on the diagram The non-metals are found on the RIGHT side of the staircase. 
 12) Which is the only non-metal element that is not located with the rest? Circle it and label it “non-metal”. HYDROGEN is the only non-metal element that is not located with the rest. 


13) Where are the metalloids found and how many of them are there? The metalloids are found directly around the staircase. There are 8 of them. 13

All solids excepts mercury State of mater METALS All solids excepts mercury

State of mater of NON -METALS Most gases except for Br which is a liquid and C, P, S, Se and I which are solids.

State of mater of METALOIDS All solids

Properties of Metals: Good conductors of heat and electricity Shiny (have luster) Malleable (bendable) Ductile (can be pulled into a wire) Some are magnetic

Properties of Nonmetals: Poor (bad) conductors of heat and electricity, non magnetic, Solids are brittle (break instead of bend) Non Malleable. Generally the opposite of metals

Metalloids: have Properties of both metals and nonmetals Metalloids: have Properties of both metals and nonmetals - B, Si, Ge, As, Sb, Te, Po, At

Chemical Reaction Equation Fe + O2  Fe2O3 Reactants products Above chemical reaction is in equation form Reactants = left side (Fe and O2) Products = right side (Fe2O3) Reaction =Chemical change! How do you know if a chemical reaction is happening?

Indicators of chemical reaction: Temperature Change (or flames) Color change Gas Forms (bubbles) Precipitation (Something solid forms, rust) Odor Change (Smell)

Summary: Metals are elements that have a luster, are malleable, and conduct electricity. Many metals react with acids and with copper (II) chloride solution. Nonmetals are usually dull in appearance, brittle, and do not conduct electricity. Most nonmetals do not react with acids or with copper (II) chloride solution. Elements that have some properties of both metals and nonmetals are metalloids.
