How did physicists start to sort out the known components

Presentation Transcript

6.1 How did scientists start to sort out the known components? Scientists utilized the properties of components to sort them into gatherings Chlorine, bromine, and iodine have fundamentally the same as synthetic properties. (Dobereiner, 1829)

6.1 Metals, Nonmetals, and Metalloids Metals, Metalloids, and Nonmetals in the Periodic Table

6.1 Metals

Physical Properties of Metals Have a high radiance ( gleaming) Solid at room temperature Are great conveyors (of warmth and electric current) Are bendable (the capacity to be maneuvered into a thin strand like wire) Are pliable (the capacity to be squeezed or beat into a thin sheet)

6.1 Metals Usage Uses of Iron, Copper, and Aluminum

6.1 Metals If a little measure of boron is blended with silicon, the blend is a decent conduit of electric current. Silicon can be cut into wafers, and used to make PC chips.

6.1 Nonmetals .

Physical Properties of Nonmetals dull radiance (not gleaming) gas at room temperature (some are not a gas at room temperature) not malleable (the capacity to be maneuvered into a thin strand like wire) Insulator (measurement not lead power) Brittle (break and smashs effectively)

6.1 Metalloids

Metalloids A metalloid for the most part has properties that are like those of metals and nonmetals. The conduct of a metalloid can be controlled by evolving conditions. The most essential utilization of metalloids is as of "semiconductors", substances who can change the measure of power that they lead - - in light of warmth, light, and so forth . . - extremely helpful in PC chips
