Question 3

Which of the following is NOT TRUE regarding the properties of metals?
A) Malleable
B) High density
C) High melting/boiling point
D) Form negative ions (anions)

A) Low density
B) Good electrical conductors
C) Low melting/boiling point
D) Form cations and anions

Answer 4

B, metals are the ones that are good electrical conductors

Question 5

Active Recall:

Describe metals, nonmetals, and metalloids

Include:
Appearance
Heat/Electrical Conductivity
Natures of oxides
Ductility
Malleability
Density
Melting/Boiling Point
Type of Ion Formed

Answer 5

Metals

Appearance

• Shiny, metallic luster

Heat/Electrical Conductivity

• Good heat/electrical conductors

Nature of oxides

• Basic

Ductiltiy

• Yes, ductile (can be compressed into thin wire)

Malleability

• Yes, malleable/flexible

Density

• High density

Melting/Boiling Point

• High melting/boiling point

Type of Ion Formed

• Cations (+), lose elections

Nonmetals

Appearance

• Dull

Heat/Electrical Conductivity

• Poor heat/electrical conductors

Nature of oxides

• Acidic

Ductiltiy

• x

Malleability

• Not malleable: brittle and breaks easily

Density

• Low density

Melting/Boiling Point

• Low melting/boiling point

Type of Ion Formed

• Cations (+) and Anions (-)

Metalloids
- ARE BOTH FOR EVERYTHING (share properities of metals and nonmetals)

Question 6

Which of the following is NOT TRUE?

A) H2O is a compound, which is a type of pure substance
B) Salt mixed with water is a hetergenous mixture
C) Oil mixed with water is a type of mixture
D) Carbon is an element which is a type of pure substance

Answer 6

B, salt mixed with water is a homogenous mixture because it is a mixture of two pure substances combined together in one substance, AND it has NO distinct boundaries

Hetergenous mixtures have disintct boundaries
