1

smallest particle of an element/mass

atom

1

a molecule with two or more different kinds of atoms

heteroatomic molecule

2

Vaporization

Liquids to gases

2

homogeneous

a mixture, one visible phase (all solid, liquid or gas) and same properties throughout

2

Anything with mass and occupies space. Gas and air are this

Matter

2

first group. soft, shiny metals that readily react with water

alkali metals / active metals

3

heteroatomic molecule

a molecule with two or more different kinds of atoms

4

alkali earth metals / active metals

2nd group. soft, shint metals the only moderately react with water

5

Gases to liquid

Condensation

6

atom

smallest particle of an element/mass

6

heterogenous

a mixture, 2 or more visble phases (solid, liquid, gas). different properties in different phases

8

Solids, liquids and gases

Physical states

8

alkali metals / active metals

first group. soft, shiny metals that readily react with water

9

Dissolved in water

Aqueous

10

Group 17. reactive elements that are gases at room temp or become gases at slightly above room temp

halogen

11

Physical states

Solids, liquids and gases

11

2 atoms of the same element bonded toghther. HOFBrINCl

diatomic

13

region of space in an electron subshell where an electron is most likely to be found. each one can accomodate 2 electrons. specific shell and subshell combo (1s, 2p, etc)

electron orbital

14

Matter

Anything with mass and occupies space. Gas and air are this

15

how close we are to the true/known value. takes precedence when multiplying/dividing sig fig's. least # of sig figs dictate our answer

accuracy

2 or more atoms that function as a unit

molecule

18

Liquids to gases

Vaporization

20

diatomic

2 atoms of the same element bonded toghther. HOFBrINCl

21

lowers energy required for a reaction, speeds up reaction

catalyst

Group 17. reactive elements that are gases at room temp or become gases at slightly above room temp

24

a mixture, one visible phase (all solid, liquid or gas) and same properties throughout

homogeneous

25

combustion reaction

forms CO2 and H2O

26

Gas to solids

Deposition
