PPT-Elements and Compounds Atoms are the fundamental building blocks of the universe.

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. Bonding. p. 144-156. Remember….. There are two kinds of pure substances. Elements. Compounds. Elements. Substance that cannot be separated or broken down into simpler substances by chemical means.. Mix and Match. Write the electron configuration for Chlorine (. Cl. ) and Magnesium (Mg) and then for their ions.. Draw a diagram of the structure of an atom.. Fill in the table:. Revision. Particle.

Hmm…I am just moving around randomly.. Before Planets. A nebula is a cloud of dust and gas in space.. . . Recognize that there are a finite number of elements and that their atoms combine in a multitude of ways to produce compounds that make up all of the living and non-living things that we encounter . 2. . How many different types of atoms is helium made up of?. 3. Draw the Bohr model for helium (there are two neutrons in helium).. Today’s Objectives. SWBAT explain that a ‘chemical formula’ describes the combination of two or more elements.. Rock, wood, air, metal, water, and animals are all matter. Matter. Elements.

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.. 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.. Dr. . Nouf. H. . Alotaibi. Group 17 elements, fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At), belong to halogen family. .
