Q

Reactants

A

The starting substances.

20
Q

Products

A

The substances formed.

21
Q

Chemical Property

A

The ability of a substance to undergo a chemical reaction and to form new substances. Burn, rot, rust, decompose, ferment, explode, and corrode.

22
Q

Law of Conservation of Mass

A

In any physical change or chemical reactoin, mass is neither created nor destroyed; it is conserved.

23
Q

freezing

A

a liquid becoming a solid due to a loss of energy; also known as solidifying

24
Q

melting

A

a solid becoming a liquid due to an increase of energy

25
Q

condensation

A

a gas becoming a liquid due to a decrease in energy

26
Q

vaporization

A

a liquid becoming a gas due to an increase of energy; could be evaporation or boiling

27
Q

ionization

A

a gas becoming electrically charged plasma due to an increase in energy

28
Q

recombination

A

a plasma becoming a non-charged gas due to a loss of energy; also called deionization

29
Q

sublimation

A

a change of state from a solid to a gas, bypassing the liquid state, due to an increase of energy; example: dry ice

30
Q

deposition

A

a change of state from a gas to a solid, bypassing the liquid state, due to a loss of energy; example: snow or frost

31
Q

Ions

A

atoms with positive and negative chart

32
Q

How many elements is periodic table made up of?

A

118 elements

33
Q

A

an atomic particle with no electric charge

36
Q

electron

A

a negatively charged atomic particle

37
Q

isotopes

A

atoms of the same element that have different numbers of neutrons but the same numbers of protons and electrons

38
Q

atomic mass

A

the sums of the masses of protons and neutrons in one atom of an element

39
Q

nonmetal

A

any element or substance that is not normal

40
Q

metal

A

a substance that is a good conductor of electricity and heat, forms cations by loss of electrons, and yields basic oxides and hydroxides

41
Q

anion

A

a negatively charged ion

42
Q

cation

A

a positively charged ion

43
Q

ionic bond

A

the bond between two oppositely charged ions

44
Q

compound

A

a substance made of two or more elements

45
Q
