12. Chemistry study guide 1. Recognize that matter is composed of extremely small particles, too small to be seen with a classroom microscope, called __atoms_. 2.Atoms are the smallest part of an __element___that has the chemical properties of the element. 3.A single atom has __mass_and takes up space. 4.Physical properties of metals include: A. Heat and electricity move through them easily __conductor_ b. Heavy for their size ____high density___________ c. Ability to be drawn into a wire ________ductile________ d. Having a shiny surface or reflecting light brightly _____luster____ e. Ability to be hammered into different shapes ____malleable_______ 5. Physical properties of nonmetals include: A. ___dull____- Not shiny B. _nonconductor____ - Heat and electricity do not move through them easily C. ___brittle_______- Break or shatter easily (solids) 6. Elements are _pure substances_ that cannot be changed into simpler substances. 7. Elements are composed of _one_ type of atom. 8. Compounds are __pure substances__ that are composed of two or more types of elements that are chemically combined.

13. 9. One way that two or more elements can combine is to form a ____chemical bond/molecule____. 10. __Mixtures__are composed of two or more different substances that retain their own individual properties and are combined physically (mixed together).Mixtures can be separated by physical means (filtration, sifting, or evaporation). 11. Mixtures may be __heterogeneous__or homogeneous. 12. In a heterogeneous mixture, which is not uniform throughout, the components can be visibly distinguished. An example is _fruit salad_. 13. In a homogenous mixture, which is uniform throughout, the substances are evenly mixed and cannot be visibly distinguished. The particles of the substances are so small that they cannot be easily seen. Another name for a homogeneous mixture is a _solution__ 14.On the periodic table there is a _zigzag_ line on the right side of the table. There are two sections of elements on the periodic table, metals and nonmetals. 15. Metals are a major classification of elements generally located on the side of the zigzag line on the _periodic_ table. a.Examples of metals are: __sodium_ (Na), Calcium (Ca), Iron (Fe), and Aluminum (Al). The majority of elements are metals. 16.Nonmetals are a major classification of elements generally located on the right side of the zigzag line on the periodic__table___. a.Examples of are: _chlorine_ (Cl), Oxygen (O), Sulfur (S), and Iodine (I).

14. Agenda 10.24.14 1. Bell \ringer: Write 7 facts about compounds. 2.Then turn in bell ringer 2.Then turn in bell ringer. Each person must turn in a paper. If you have no bell ringers then state that on a sheet of paper with your heading on it. 3. Now, we will explore the research sites for element samples.
