Semester Exam Review Part 2

Metals, Nonmetals, Metalloids

A review

Metals

• Almost all elements on the left side and middle of the table

• Majority (75%) of the elements are metals

• Examples: Magnesium, Calcium, Copper, Silver, Gold, Nickle

• There are different types of metals, but for now we will focus on it as a general group

Physical Properties of Metals

• Luster - Shines, reflects light

• Great Conductivity - How well electricity and heat travels through the element

• Malleable - Can be beaten into different shapes without breaking

• Ductile - Turned into wires

• Solid at room temperature - Except for Mercury

Multiple Select

Check off all properties of metal you can observe in this image of US coins.

• Luster

• Malleable

• Conductivity

• Ductile

• Solid at room temperature

Nonmetals

• All elements on the far right side of the table + hydrogen

• Second largest grouping of elements

• Examples: Carbon, Nitrogen, Neon, Helium, Hydrogen

• There are three divisions of nonmetals, but we will focus on the general group

Properties of Nonmetals

• Essentially, they are the opposite of metals

• Dull, not shiny

• Brittle when solid

• Some are gasses

• NOT malleable, conductive, or ductile

Multiple Select

Check off all of the nonmetal physical properties you can observe in this image of sulfur.

• Dull appearance

• Brittle solid

• Gaseous

• Not malleable

Metalloids

• Found in the "staircase" separating metals and nonmetals. Starting at B (boron)

• The smallest amount of elements on the table

• Examples: Boron, Silicon, Arsenic

Properties of Metalloids

• Properties are between metals and nonmetals 

• Can have a metallic luster, or be dull

• Conductive, but less than metals

• Solid at room temperature, but more brittle than metals

• Usually malleable and ductile

Open Ended

Look up everyday uses of metalloids. List one element and how we use it.
