The Great Eight Chasity Lynn Nichols

Alkali Metals  Members of the family: Lithium, Sodium, Potassium, Rubidium, Caesium, Francium  Five Facts: 1.This group lies in the s-block of the periodic table 2.they are all shiny, soft, and highly reactive 3. All the alkali metals react with water 4. All the discovered alkali metals occur in nature 5. alkali metals are not essential This image shows where the alkali metals are located on the periodic table Olympic gold metal to show that the alkali metals are the first family

Alkali Earth Metals  Members of the family: beryllium, magnesium, calcium, stronium, barium, radium  Five facts: 1.they all have two valence electrons 2.Magnesium plays a key role in the process that uses sunlight to produce sugar in plants 3.metals in this group are stronger than the metals in the Alkali metals group 4.differences in reactivity among the alkali earth metals are shown by the ways they react with water 5.magnesium and calcium provide materials used for transportation and construction To show where the alkali earth metals are located Silver to show that the alkali earth metals are the second group

The Boron Family  Members of the family: Boron, Aluminum, Gallium, Indium, Thallium  Five Facts: 1.all these have three valence electrons 2.aluminum is the most abundant metal in the earths crust 3. Several group 13 elements have biological roles in the ecosystem 4. these are also referred to as icosagens and triels 5. they do not occur elementally in nature To show where the boron family is located on the periodic table Bronze to symbolize that the boron family is the third family

The Carbon Family  Members of the family: Carbon, Silicon, Germanium, tin, lead  Five Facts: 1.this Group contains a nonmetal, two metalloids, and two metals 2. Each elemant in this group has four valence electrons 3. the metallic nature of the elements increases from top to bottom within the group 4. germanium is a better conductor of electric current than silicon 5. except for water most of the elements in the human body conatain carbon To show that the carbon family is the fourth family To show where the carbon family is located on the periodic table

The Nitrogen Family (Group 5A)  Members of the family: Nitrogen, Phosphorus, Arsenic, Antimony, Bismuth  Five Facts: 1. this group contains two nonmetals, two metalloids, and one metal 2. all the elements in this group have five valence electrons 3. Antimony and bismuth can exist with a -3 charge in compound but are more commonly found as metals with a +5 charge because of their size 4. electrons are more easily stripped off than they are able to attract 5. Arsenic and antimony are most commonly found in alloys used for the production of batteries To show where they are located on the periodic table To show that this family is the 5 th family

The Oxygen Family  Members Of the family: Oxygen, Sulfur, Selenium, Tellurium, Polonium  Five Facts: 1. Each has six of the desired eight electrons required for the octet in its highest energy level 2. it takes or accepts two electrons from atoms of other elements to form anions or shares two electrons to form covalent bon 3. Oxygen and sulfur are common elements 4. tend to exist as diatomic and polyatomic molecules, such as 02, 03, S6, S8, and Se8 5. Occur elementally in nature and in combined states To symbolize that this family is the 6 th family To show where they are located on the periodic table

The Halogens  Members of the family: Fluorine, Chlorine, Bromine, Iodine, Astatine  Five Facts: 1. The halogens can be found on the left-hand side of the noble gases 2. Halogens form diatomic molecules 3. halogen elements have seven valence electrons 4. halogens readily combine with most elements and are never seen uncombined in nature 5. All halogens form sodium salts that have similar properties To show where this family is located on the periodic table To symbolize that this is the 7 th family

The Nobel Gases  Members of the family: Helliumm, Neon, Argon, Krypton, Xenon, Radon  Five Facts: 1.theyre all colorless, odorles and tasteless, unless influenced by other chemicals 2. Noble Gases are also call "Rare" Gases, Inert Gases or "Royal" Gases 3. All elements in this family are considered inactive 4. The Noble Gases all have an extremely low melting point 5. Scientist Sir William Ramsay found all noble gases except radon To show where the nobel gases are found on the periodic table To show that the Nobel gases are the 8 th family
