Chapter 10. The Periodic Table. Early Attempts at Classification. Johann Dobereiner. German chemist – 1817 He found the properties of metals Ca, Ba and Sr were very similar. He also noted the atomic mass of Sr was about midway between those of Ca and Ba. He grouped elements into triads.

Precipitation Reactions

Precipitation Reactions

Precipitation Reactions. When one mixes ions that form compounds that are insoluble (as could be predicted by the solubility guidelines), a precipitate is formed. Metathesis comes from a Greek word that means “to transpose”. AgNO 3 ( aq ) + KCl ( aq )  AgCl ( s ) + KNO 3 ( aq ).

Matter:

Matter:

Matter:. It’s what the world’s made of. An atom refresher. Matter is anything that takes up space (or has volume) and has mass. All matter is made of atoms Atoms are the building blocks of matter, somewhat like how bricks are the building blocks of houses. www.powersof10.com.

THE PERIODIC TABLE

THE PERIODIC TABLE

THE PERIODIC TABLE. is arranged in order of increasing number of protons . the atomic number of an element is the number of protons in the nucleus and the number of electrons in a neutral atom. the atomic weight increases with increasing number of protons and neutrons.

Elements are arranged:

Elements are arranged:

Vertically into Groups. Horizontally Into Periods. Elements are arranged:. Why?. If you looked at one atom of every element in a group you would see…. Each atom has the same number of electrons in it’s outermost shell. An example….
