1

What is a physical property?

A characteristic that can be observed or measured

2

Talk about the physical properties of metals

Shiny
High melting and boiling points
Solid at room temp
Malleable
Ductile
Good conductors

3

Talk about the physical properties of non metals

Dull
Usually low melting and boiling points
Half are solid and half are gas at room temp
Brittle
Non ductile
Poor conductors

4

Where are metal elements placed on the periodic table?

On the left hand side

5

Where are non metals placed on the periodic table?

On the right hand side

6

What is a chemical property?

A characteristic of a substance that can only be determined by studying its chemical reactions

7

Can metals react with each other?

No

8

What is an alloy?

A mixture of metals

9

Talk about how metals and electrons interact with each other

Metals can lose electrons to make positive ions while non-metals can gain electrons to make negative ions

10

Can non-metals react with each other?

Yes, they create compounds

11

If a metal oxide dissolves in water, what happens?

An alkaline solution is produced

12

If a non-metal oxide dissolves in water, what happens?

An acidic solution is created

13

Describe the appearance of metals and non-metals

Metals - shiny
Non metals - dull

14

Describe the melting point and boiling point of metals and non metals

Metals - usually high
Non metals - usually low

15

What are metal’s and non metal’s states at room temperature?

Metal - solid
Non metal - half of substances gas, half of substances solid

16

Metal - solid
Non metal - half of substances gas, half of substances solid

Metals - malleable (they bend without shattering)
Non metals - brittle (they shatter when hammered)
