Document Summary
Chem 1601 test 1 study guide (chapters 2. 6-5. 7) Chapter 2. 6 subatomic particles: protons, neutrons, and electrons in atoms. The number of protons defines the element atomic number. Atomic numbers range from 1 to 116. Elements in the same column in the periodic table are in the same group and have similar properties. Isotopes: atoms with the same number of protons but a different number or neutrons. Natural abundances: the percentage at which different isotopes occur in a random sample. Chapter 2. 7 finding patterns: the periodic law and the periodic table. Periodic table comes from dmitri mendeleev (1834-1907) Periodic law: when the elements are arranged in order of increasing mass, certain sets of properties recur periodically. Metals: good conductors of heat and electricity, malleable, ductile, usually shiny, and tend to lose electrons when undergoing chemical changes. Nonmetals: poor conductors of heat and electricity and tend to gain electrons when undergoing chemical changes.
