Metal |
Shiny, Malleable, Ductile, good conductors, solid at room temp (except mercury), usually denser than non-metals, active-react w/acid; very active- react w/water |
Ex. Iron, Copper, Nickel, Lead |
|
Non-metals |
Dull, brittle, lower melt/boil points than metals, gasses at room temp, poor conductors |
Fluorine, Phosphorus, Chlorine, Iodine |
|
Metalloids |
Don't fit in either group (have properties of both), semi conductors |
Ex. Silicon, Arsenic, Germanium, Antimony |

Four Main Ideas |
•Ancient Chemistry gave practical info on matter but not good undersanding •The first modern chemists found and named new elements •Elements = metals, non-metals, and metalloids •the PT orders the elements in rows based on mass and groups/columns of similar properties |
|
|
Ancient Chemistry |
Find & purify as many new elements as possible |

|
|
Alchemists |
Reflection on religious beliefs & attempt to blend natural and spiritual worlds |
|
|
Beginning of Modern Chemistry |
Experimentation & observation become more important. Realized existence of compounds & elements |
|
|
Berzelius |
Symbolic system to describe elements: 1) labeled by first letter of English or Latin name 2) if first letter used already, use first & second 3) first letter capital, second letter lowercase |
|
|
Mendeleev |
Ordered elements by mass, properties repeated, put in groups w/ both, left gaps when heaviest element didn't match w/properties |

|
|
Dalton |
Discovered masses of elements in chemical reactions had certain proportions, figured out masses from that |
After chemical reaction, mass of oxygen is 8 times hydrogen, meaning oxygen is 16 times mass of hydrogen (one part oxygen, two parts hydrogen) |
|
Predicting |
Gaps specific w/ mass and properties, scientists could try to find right element or right mass if mass & properties not perfect |
|

1700s- 20 1800s- 51 |
|
|
What did the first modern chemists do that was different from Alchemists |
Test theories and observations/experiment, test substances to see if they could be broken down and found in what proportions |
