32
Q

Nucleus contains:

A

protons and neutrons

33
Q

Where are electrons located?

A

orbit outside the nucleus

34
Q

Atomic Mass =

A

the average mass of an atom in an element

35
Q

Number of protons =

A

number of electrons

36
Q

How do you find the number of neutrons?

A

mass number - protons

37
Q

How do you find the atomic mass?

A

protons + neutrons

38
Q

Why aren’t electrons included in the atomic mass

A

electron mass is very tiny compared to protons and neutron mass

39
Q

What is an Isotope?

A

two of the same element with/ the same number of protons, and electrons, but different neutrons

40
Q

What is electron configuration?

A

identify the location of the electrons of an atom

41

47
Q

Subshell orbitals are organized from

A

lowest to highest energy

48
Q

Valence electrons

A

are electrons in the outermost shell that have the most energy

49
Q

Octet rule

A

element seeks to have 8 electrons in its outermost energy shell

50
Q

Order of subshell filing:

A

1s,2s,2p,3s,3p,4p

51
Q

Atomic radius

A

measure from the center of the nucleus to the outermost electron

52
Q

Electronegativity

A

measures how strongly an atom attracts electrons

53
Q

What element has the highest electronegativity?

A

Fluorine

54
Q

Ionization energy

A

how much energy is require to remove an electron from an atom

55
Q

Ionic bonds

A

one atom loses electron to another atom

56
Q

Cation =

A

positive charge

57
Q

Anion =

A

negative charge

58
Q

Electrostatic charge

A

bond form b/c the positive charge is attracted to the negative charge

59
Q

Salt is formed by

A

ionic bonds (metal +nonmetal)

60
Q

Naming ionic compound

A

cation name goes first then anion (-ide or -ate)

61
Q

Monoatomic(anion)

A

-ide (made of one type of anion)

62
Q

Polyatomic(anion)

A

-ate (made of more than 1 type of anion)

63
Q

Covalent bonds

A

two atoms share electrons(form when atoms have equal amount of electronegativities)

64

A

stronger than ionic bonds

70
Q

Hydrogen bonds

A

the force of attraction between a hydrogen and an electrogative

71
Q

Cohesive

A

two molecules stick to each other (water)

72
Q

Adhesive

A

water is attracted to other substances

73
Q

Chemical reactions

A

one or more substances (reactants) are converted to different substances (products)

74
Q

Subscript number

A

tells you how many atoms are in that molecule

75
Q

Coefficient number

A

the BIG number before the molecule tells you how many molecules you have.

76
Q

How to find the total amount of hydrogen atoms:

A

multiply the coefficient x the subscript number

77
