Classes of Elements ( Pages 244 – 245)
Properties Properties = observations you can make about something. Example = what are the properties of a football?
Most metals share these properties… 1.Shiny 2.Ductile 3.Good Conductors of Electricity 4.Malleable 5.Good Conductors of Thermal Energy 6.Solid at room temperature
SHINY You can see your reflection in a mirror because mirrors have a thin layer of silver (Ag) behind the glass.
DUCTILE Most metals are ductile, which means they can be made into thin wires.
Good CONDUCTORS of electricity Wires in electrical devices in your home are made of copper.
MALLEABLE Most metals are malleable, which means they can be flattened into thin sheets or formed into shapes without shattering. Aluminum (Al) can be flattened into sheets to make foil and cans.
Good CONDUCTORS of thermal energy Most metals are good at transferring heat. Iron (Fe) griddles conduct thermal energy from a stove top to cook food.
Most metals are solids at room temperature Lithium (Li) Zinc (Zn) Nickel (Ni) Sodium (Na) Gold (Au Calcium (Ca)
Most nonmetals have these properties… 1.Not shiny 2.Not ductile 3.Not good conductors of electricity 4.Not malleable 5.Not good conductors of thermal energy 6.Gases at room temperature
Most nonmetals are gases at room temperature Neon (Ne) Helium (He) Argon (Ar) Hydrogen (H) Nitrogen (N)
Metalloids are known as semi- conductors. This means that they can conduct electricity depending on their temperature. Metalloids share some properties of metals and some properties of non- metals.
Boron (B) Silicon (Si) Arsenic (As)

The Periodic Table Part I – Categories of Elements.
Alkali Metals Nobel Gases Halides Non Metals
Chemistry: Elements Chapter 5. Elements Elements- Substances that cannot be broken down into a simpler substance. – Remember that elements are only made.

Elements and Symbols Practice. PART I (SLIDES WITH BLUE BACKGROUNDS) Directions: Name the Symbol for each listed element.
Concept:. Periodic table Group/family period Metalloid Metal Transition element Non-metal.
Periodic Table of Elements. Elements Science has come along way since Aristotle’s theory of Air, Water, Fire, and Earth. Scientists have identified 90.
Notes:. 1. Metals 2. Metalloids (semimetals) 3. Nonmetals.
Chapter 5 The Periodic Table. Mendeleev’s Periodic Table Mendeleev arranged the elements into rows in order of increasing mass so that elements with similar.
Elements An element is a pure substance that cannot be separated into simpler substances by physical or chemical means An element is a pure substance that.
Elements can be divided into metals non-metals Aluminium is a typical metal Chlorine is a gas at room temperature and pressure.
Periodic Table – Elements Elements are pure substances made up of atoms that cannot be broken down. These Elements are categorized by characteristics as:
Give the symbol for each element listed below. 1.Silicon 2.Uranium 3.Carbon 4.Magnesium 5.Sodium 6.Calcium 7.Hydrogen 8.Sulfur 9.Lead 10.Helium 11.Mercury.
METALS, NONMETALS, METALLOIDS, & NOBLE GASES FOUR SECTION FOLDABLE ADVANCED ORGANIZER.
The Periodic Table. Periodic Table – Arrangement of all elements – Mendeleev 1 st to see pattern of elements and arranged according to these patterns.
+ Chapter 7 The Periodic Table Chapter Organizing the Elements Prior to 1860 There were 63 known elements No know pattern had been determined.
Element Symbol Practice. Carbon C Potassium K Beryllium Be.
H. Hydrogen O OXYGEN Al Aluminum Kr Krypton.
Characteristic Properties of Metals Good electrical conductors and heat conductors. Malleable - can be beaten into thin sheets. Ductile - can be stretched.
The Nature of Matter K 1.2 The Simplest Matter. The Simplest Matter An element is matter made of only one kind of atom. An element is matter made of only.
Metals Next Aluminum (Al) Gold (Au) Metals are on the left side of the periodic table. They are malleable (can be pounded or rolled into sheets without.
Use the following slides to help fill out the periodic table. You will be able to use this periodic table on your test next week. Make sure you answer.
Properties of Metals Metals are good conductors of heat and electricity. Metals are shiny. Metals are ductile (can be stretched into thin wires). Metals.
Chapter 2: Elements are the building blocks of matter. Grade 9 Science Unit 1: Atoms, Elements, and Compounds.
Important Terms: Element: A pure substance that cannot be broken down into a simpler chemical substance The building blocks of all substances Ex. silver.
Metals, Nonmetals, Metalloids. Metals Solid (except for mercury, a liquid) Shiny/Metallic Luster Good conductors of thermal energy (heat) & electricity.
Chemistry Basics Metals, Metalloids, Non-Metals. Grouping of Elements As we have discussed in class, elements on the periodic table can be broken down.
All atoms of this element contain 36 protons.. This element contains protons and neutrons.
Note Guide 2-2 day 2 4. Atomic Mass – an average of all the elements isotopes (different # of neutrons compared to protons) Classes of Elements – 3 main.
Periodic Table of Elements Properties. Dmitri Mendeleev Born: Siberia in 1834 and died in Mendeleev is best known for his work on the periodic table;
The Periodic Table October 17, In 1869 he published a table of the elements organized by increasing atomic mass by the way they reacted.
Atoms and Elements. Atoms Atoms are the “building blocks” of all matter and are the simplest form of molecule. They are all made up of protons, neutrons.
