What do you know question: What do you know about where metals in the periodic table are located? Teach the teacher questions: So far what has been your favorite activity and what has been your least fave?

Review: Looking at your periodic table, tell me everything you know about neon? Teach the Teacher: If you could be an animal, what animal would you be?

What is the contribution? (ex: gold panning or antibiotics) (bigger font) How it is used/made, or what it is? What tribe or region used/discovered it? Another interesting fact Add a picture Contributions: gold plating, antiasthmatic medication, diabetes medication, anesthetics

Most elements are metals. 88 elements found to the LEFT of the Zigzag Line

Luster (shininess) Good conductors of heat and electricity High density (heavy for their size) High melting point Ductile (drawn out into thin wires) Malleable (hammered into thin sheets)

Easily lose electrons (positive ions CATIONS) Corrode easily React easily with other elements React easily

First metal used was gold – 6000 years ago Followed by Cu Ag Sn Fe Al was not refined until 1800’s Hg mercury is the only metal that is a liquid at room temp

Soft metals – they can be cut with a knife Most reactive of all the metals - React rapidly with oxygen and water Do not occur in nature in their elemental form Stored under oil Will form a +1 ion by giving away their one valence electron

Lithium Li Sodium Na Potassium K Rubidium Rb Cesium Cs Francium Fr Extremely Rare Radioactive

Do not occur in nature in their elemental form Will form a +2 ion by giving away their two valence electrons Uses Fireworks Ca – Bones & Teeth Ba - X-Rays

Beryllium Be Magnesium Mg Calcium Ca Strontium Sr Barium Ba Strontium Sr Radium Ra

These elements are most familiar to the public because they are found in nature in their elemental form Often form colored compounds Chromium precious gems (emeralds and rubies) Cadmium yellow Cobalt blue

Iron Triad Steel Fe most widely used metal 2 nd most abundant in the earth’s crust

Review questions: Tell me as many physical characteristics of metals as you can remember (or use your notes). Teach the teacher questions: Best pair of shoes that you have ever owned. Learning Targets: What metalloids are. Identify valence electrons on periodic table Identify where non-metals are

On the front write: Luster On the back write: Shineness

On the front write: Malleable On the back write: Ability to be hammered and re- shaped

Copper Silver and Gold Group 11 Coinage metals Cu - wiring Ag – photographs

Zinc Cadmium and Mercury Coat or Plate metals Batteries Thermometers

Lanthanides Elements 58 – 71 Elements used in motion pictures industry Produce colors you see on the TV Actinides Elements 90 – 103 All actinides are radioactive and unstable Thorium and Uranium are found in the earth’s crust Uranium – nuclear reactors

Found to the RIGHT of the zigzag line Hydrogen is considered a nonmetal Group 18 – Noble Gasses are the only group that consists of all nonmetals Group 17 - Halogens Properties Nonmetals gain electrons to become stable – anions Most are gasses at room temp Not malleable Not ductile Poor conductors of heat and electricity No Luster – Dull Important nonmetals in Humans Carbon Hydrogen Nitrogen & Oxygen

Metalloids conduct electricity better than nonmetals, but not as well as metals. Metalloids conduct electricity better than nonmetals, but not as well as metals. Synthetic elements do not occur naturally (they are man-made) Synthetic elements do not occur naturally (they are man-made) All elements with an atomic number higher than uranium (92) were made by scientists and most are radioactive. All elements with an atomic number higher than uranium (92) were made by scientists and most are radioactive.

Representative Elements in: Number of Valence Electrons Group IAall elements have 1 valence electron Group IIAall elements have 2 valence electrons Group IIIAall elements have 3 valence electrons Group IVAall elements have 4 valence electrons Group VAall elements have 5 valence electrons Group VIAall elements have 6 valence electrons Group VIIAall elements have 7 valence electrons Group VIIIAall elements have 8 valence electrons The Lewis electron-dot diagrams focus on the electrons in the highest energy level in the atom, the valence electrons.energy level Valence electrons are the electrons that participate in chemical reactions. Lewis Dot Diagrams

Lewis Dot uses the symbol of the element and dots to illustrate the number of electrons in the outermost energy level Dots are placed in 8 positions around the symbol 2 spots for each Right Left Top & Bottom Elements of the same group (column) have the same number of valence electrons
