Identifying Elements Through Properties
Explore how to differentiate between metals, non-metals, and metalloids using characteristic properties. Learn how properties can help determine the identity of an element, and understand the key characteristics of each type of element. Discover the unique set of properties that define elements and how these properties remain consistent regardless of the amount of the substance present.

Elements Chapter 3 Section 1
Lesson Objectives Define Element and characteristic property Use properties to determine the identity of an element Differentiate between a metal, non-metal, and metalloid
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Element Characteristic Properties Metal Non-metal metalloid
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Element Element Pure substance that cannot be broken down into simpler substances Pure substance only one type of particle
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Characteristic Properties Characteristic properties unique set of properties that can help you identify it No matter how much of a substance is present, if it is the same element it will have the same properties 1 atom of gold has the same properties as 100,000,000 atoms of gold````
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Characteristic Properties Chemical Flammability reactivity with acids Toxicity Combustion Physical Density Solubility melting point color mass
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Characteristic Properties Identifying Elements
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Characteristic Properties An unknown gray substance was tested and has a density of 2.3 g/cm3. What is the substance? Element Density Boiling point ( C) 280 Melting point ( C) 44.1 Mass Color g/cm3 1.82 (amu) 30.9 Phosphorus white Silicon Selenium 2.3 293.0 2355 684.9 1410 217.0 28.0 78.9 gray gray
Are you now able to. Define element and characteristic properties . I still feel unsure. I need some more help to understand. I feel ok. I need to do some more work on my own to check my understanding. I am happy and feel I understand and can explain the main points.
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Metals, Non-Metals and Metalloids Elements can be divided into three categories: Metals Non-Metals Metalloids
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Metals Metals Most elements are metals Shiny Good conductors of heat and electricity Malleable Ductile
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Non-Metals Non-Metals Dull (not shiny) Poor conductors of heat and electricity Brittle Unmalleable Carbon Fluorine Sulfur
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Metalloids Metalloids Have properties of both metals and non-metals What properties they have depend on the particular metalloid. Also known as semi- conductors
Differentiate between a metal, non-metal, and metalloid Use properties to determine the identity of an element Define element and characteristic property Keywords: Metals, Non-Metals or Metalloids? Metal Non-Metal Metal Metalloid
Are you now able to. I still feel unsure. I need some more help to understand. I feel ok. I need to do some more work on my own to check my understanding. I am happy and feel I understand and can explain the main points.
