7

35
Q

how many chem reactions are there

A

5
formation
decomposition
single replacement
double replaecment
hydrocarbon combustion

36
Q

When looking at the solubility table do you look for the anion first or the cation

A

You fist look for the anion across the top then look for the positive ion (cation)

37
Q

When balancing equations when nothing is after elements what does that stand for

A

It stands for the element being equal to 1

38
Q

what type of reaction is x+y—->xy

A

formation

39
Q

what type of reaction is xy—–>x+y

A

hydrocarbon combustion

43
Q

What chem reaction has two compounds

A

double replacement

44
Q

What chem reaction has 1 elements and 2 compounds

A

single replacement

45
Q

What chem reaction has two elements

A

formation

46
Q

what order do you use to solve hydrocarbon combustion

A

1)carbon
2) hydro
3) oxygen

47
Q

how do you find valance electrons

A

by looking at group number if the group number is in teens than its the last digit

example) cesium (group 1 ) = 1 valance electrons

48
Q

why do ionic compounds have high melting points

A

because the bonds are stronger between negative and positive because they attract better

49
Q

why are molecular compounds not electrolytic

A

because they are weak and ionize only slightly or not at all

50
Q

what is nucular notion

A

shows element symbol with mass number on the top left and atomic on the bottem left

51
Q

what is the heaviest halogen

A

astatine

52
Q

isotopes have same number of what and different what

A

same number of protons different number of neutrons

53
Q

ernest rusherford found out what

A

nucleus is made up of protons and neutrons

54
Q

what way are the periods on the periodic table side to side or up and down?

A

side to side group number is up and down

55
Q

how do you make a Lewis dot diagram

A

1) find group number if in teens then use 2nd number
2) put dots around going right

56
Q

crystal lattice def

A

ions/ ionic compounds arranged in repeating patterns called crystal lattice

57
Q

malleable def

A

can be shaped by pressure

58
Q

ductile def

A

can be stretched into a wire

59
Q

how to find how many energy levels are needed in bohr diagrams

A

period number = energy levels

60
Q

what do group numbers represent in bohr diagrams

A

the group number represents how many electrons are on the outer level

61
Q

isotopes have the same number of what and different number of what

A

same number of protons different number of neutrons

62
Q

Covalent meaning

A

It means sharing

63
Q

when drawing a diagram for a element ion what extra steps do you take

A

find out if non metal ( gains) or metal (losses)

then look at number with element bellow to determine how much electrons are being gained/lost

64
Q

metal + polyatiomic is it ionic or molecular

A

ionic

65
Q

what happens when you litmus test ionic and molecular

A

stays the same color

66
Q

when a element ends with number it stands for what

ex flourine-21

A

mass number and you need to sub protons to get your new neutrons

67
Q

what theory did dalton come up with

A

the dalton ball theory

68
Q

who came up with cathode rays

A

jj thomson

69
Q

who came up with alpha particals

A

ernest rutherford

70
Q

what do you look at to find the heavier element

A

the mass number

71
Q

isotopes have same atomic number and what else

A

same protons

72
Q

isotopes have difference numbers of neutrons and what else

A

different mass number

73
Q

how to tell if a element is neutral

A

same protons and electrons ( not an ion )

74
Q

Diffrence between ion and isotopes

A

Ion is same number of protons with the electrons varying and isotopes are same number of protons diffrent neutrons

75
Q

what are traits of ionic compounds

A

-solid at room temp

-don’t conduct as solids
-when melted or dissolved they can conduct electricity

76
Q

what are traits of molecular compounds

A

-solids, liquid or gas at room temp
-low melting points
-don’t conduct as solids
-when melted/dissolved cant conduct electricity
