PPT-1 Topic 2 Atoms, Elements, Molecules, Ions, and Compounds

Early in the 19 th century John Dalton developed atomic theory His theory explained the best available experimental data at that time His theory has been modified since then with the discovery of other data but his work was the initial ground work that we will examine first.

Early in the 19. th. century John Dalton developed atomic theory. His theory explained the best available experimental data at that time. His theory has been modified since then with the discovery of other data, but his work was the initial ground work that we will examine first.. How elements become charged. How elements become charged. ION – A charged atom. All elements on the periodic table are NEUTRAL because they have the same number of . protons (+) and electrons (-). Unit 3. Biochemistry.

Students will investigate our current understanding of the atom. b. Compare and contrast ionic and covalent bonds in terms of electron movement.. SPS2. Students will explore the nature of matter, its classification and its system for naming types of matter. For Example: If you have a piece of gold and cut it into smaller and . smaller pieces, . you would eventually reach a point where you couldn’t cut the gold up any smaller. That smallest piece would be an atom of gold.. They can be joined together by . chemical bonds. From last lesson:. Atoms can have different numbers of protons, neutrons and electrons.. There are 118 different types of atoms.. They can be found on the periodic table of elements.. DE Chemistry. Dr. Walker. Timeline. B.C.. 400 B.C. . Demokritos. and .
