1. Monday, May 13 th Entry Task Decide if the following statements are true or false. If they are true write them down as is, if they are false write down a correct statement 1.Groups on the periodic table are horizontal. 2.As you go from right to left on the periodic table the number of protons in each atom increase. 3.Sodium and Francium are in the same period. 4.Bromine is heavier than oxygen. Schedule: Understand the periodic table notes Homework: Complete tasks not completed in class Objective: I can understand that the periodic table is a map of elements organized by properties

2. Things to know before learning characteristics of groups Reactive- how likely an element is to undergo a chemical change Rule of 8 Elements like to have 8 electrons orbiting in the outside electron shell Group numbers can tell you how many electrons are in the outer shell –Group 1- has 1 –Group 2- has 2 –Group 13- has 3 –Group 14- has 4 –Group 15-has 5 –Group 16- has 6 – group 17- has 7 – group 18- has 8 If a group has less than 4 they give up their electrons- making them + ions If a group has more than 4 they take electrons- making them – ions If they have 4 they can do either What they do with their electrons determines what other elements they bond with –Oxygen has 6 electrons and Hydrogen has 1 electron –H 2 O is two hydrogen (2 electrons) and one oxygen (6 electrons) 2 electrons+6 electrons is 8! IT’S A HAPPY MOLECULE!

3. Metals Most elements are metals Elements that conduct electricity and heat well and have a shiny appearance Shaped easily by pounding, bending or being drawn into a long wire Solid at room temperature-except for mercury which is a liquid

4. Alkali metals Metals in group 1 of the periodic table Very reactive React with air –When sodium and potassium are exposed to air they react rapidly with oxygen and water vapor Usually lose en electron when bonding with other elements Ions Na + and K + are essential for functioning living cells

5. Alkaline Earth Metals Group 2 Less reactive than alkali metals but still more reactive than others Lost two electrons when bonding with other elements Calcium ions are an essential part of your diet Magnesium is a strong but light metal

6. Transition Metals Groups 3-12 Less reactive than other metals but can have some (very little bit) reactivity Metals of the earliest known elements –Copper, gold, silver and iron –Gold and silver are easily shaped Money is made from these –dine-and quarters are made of copper and nickel –Pennies are made of zinc with a coating of copper Found in foods you eat Two or more can be combined to form an alloy –Alloy can be stronger and less likely to corrode –Brass is an alloy of copper and zinc

7. Rare Earth Elements (Lanthanides) Series 58-71 Called rare earth elements because scientists once thought that these elements were available only in tiny amounts on Earth’s crust Not so rare- just hard to isolate in it’s pure form Europium is used as a coating for some TV tubes Praseodymium is used in welding helmets and protects from the harmful radiation of welding.

8. Actinides Series 90-103 Radioactive elements Very reactive Thorium and uranium are the only ones found in Earth’s crust in larger quantities Electron sharing is random- no trend

9. Nonmetals and Metalloids Nonmetals- –elements on the right of the periodic table –Properties are opposite of metals –Their properties vary more from element to element than the properties of metals –All are gas in their natural state at room temperature except for bromine which is a liquid –Poor conductors of heat and electric current Metalloids- –Properties of both metals and nonmetals –Zigzag line that separates metals from nonmetals –Semiconductors-special materials that conduct electricity under some conditions and not under others

10. Chalcogens Group 16 Also known as the oxygen family Take 2 electrons when bonding with another element One is radioactive Oxygen is what we are most made up of Sulfur smells like rotten egg

11. Halogens Group 17 Greek – means forming salts Very reactive Non metals Easily form compounds called salts with many metals Often used to kill harmful microorganisms Chlorine Iodine used in hospitals

12. Noble Gases Group 18 Do not give up or take any electrons They are considered noble, or inert because they almost never react with other elements Argon gas makes up 1% of the atmosphere Colorful lights are made by passing an electric current through tubes filled with neon, krypton, xenon or argon gas
