2: Density, Physical Change, Chemical Change, Metals, Non-metals, Metalloids

Question 0

What are some physical changes?

Answer 0

Texture, color, temperature, shape, change of state (boiling point and melting point are significant factors in determining this change.)

Question 1

How can you find density?

Answer 1

p = m/v

Where p is the density, m is the mass, and v is the volume.

Question 2

What are some chemical changes?

Answer 2

Change in temperature, change in color, noticeable odor (after reaction has begun), GAS, PRECIPITATE, HEAT ABSORBED/GIVEN OFF, LIGHT/ ELECTRICITY

Question 3

What are some properties of metals?

Answer 3

Lustrous, ductile, malleable, good conductors of heat and electricity

Question 4

What are some properties of non-metals

Answer 4

Dull, brittle, poor conductors

Question 5

What are some properties of metalloids?

Answer 5

They have either metal or non-metal traits depending on condition.
