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. Chapter 2 BLB 12. th. Expectations. Recognize important steps in the discovery of the atom and its structure.. Work with isotopes.. Learn about the periodic table.. Differentiate between molecular and ionic compounds.. Unit 3. Biochemistry. Kasprowicz. /Squires. Topic 1: Matter . . anything that has . MASS. and . TAKES UP SPACE . (has volume). Examples:. Topic 1: Matter . Topic 1: Matter . . MASS. . is the amount of matter in an . What’s all matter made of?. ATOMS!. CAN YOU TELL ME WHAT TYPE OF ELEMENT THIS IS?. ATOMS!. CAN YOU TELL ME WHAT TYPE OF ELEMENT THIS IS? . BERYLLIUM. the only atom with FOUR PROTONS(+)=ATOMIC NUMBER: 4. 22.1 Hydrocarbons. Organic Chemistry. includes almost all carbon compounds. Not limited to compounds found in living cells. Hydrocarbon: organic compound made of only hydrogen and carbon atoms. hydrocarbons. Matter and Atoms. Matter is anything that takes up space and has mass. There are 4 phases of matter solid, liquid, gas, and plasma.. All matter is made of atoms.. Atoms are the building blocks of matter, sort of how bricks are the building blocks of houses.. 2. , is used in the processing and bleaching of pulp from wood fibers and recycled cardboard. .. Learning . Goal . Write the name and formula for an ionic compound containing a polyatomic ion.. Polyatomic Ions. Rock, wood, air, metal, water, and animals are all matter. Matter. Elements. The various forms of matter are composed of one or more chemical elements. . An . element. is a pure substance that cannot be broken down into other substances by chemical means. . Dr John Mitchell.

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.. Non living matter and minerals found on earth. The distinction between the organic and inorganic are not . a. bsolute ,but there is much overlap.. It has many applications in every aspect of pharmacy including catalysis in drug synthesis, pigments, surfactants and agriculture. Dr. . Nouf. H. . Alotaibi. Group 17 elements, fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At), belong to halogen family. . Electron configurations ns. 2. np. 5.

Waals . bonds are so weak that they can be easily broken by the slightest pressure between two fingers, resulting in the sheets sliding over each other. This property is responsible for the softness of graphite and the greasy feeling one experiences when rubbing graphite between ones fingers. . They can be joined together by . chemical bonds.
