Step 1 of 3

Chapter 3: Elements and the Periodic Table 3.1 The Building Blocks of Matter A. The Atom –Dalton’s atomic theory (1802) • An _atom_is the smallest particle of matter_. • An _atom is the smallest unit of an element . • Atoms of one element are _(mostly) identical__. • Atoms one element are _different_ from atoms of _another element_. B. Elemental Symbols • A symbol represents each element. • Some are easy: C H Carbon Hydrogen • Some are harder to see: Au Sn Gold Tin • Know name = symbol for #1 - 20 for Test 1__; Know the entire list from Moodle for __Test 2__. C. Compounds are made up of __2 or more elements_ joined by chemical bonds__. H2O C2H6O • The smallest unit of a compound is a _molecule_. • _Subscripts_ are whole numbers that show _how many_ __atoms___ of each element are present in each molecule of the compound. Bad: HO1/2 C0.33HO0.18 • All molecules of a compound are _identical_. D. Smallest Form 1. Most elements are _monoatomic__: the smallest form is a singular atom. 2. __Diatomic Elements__: elements whose smallest unit is a __2 atom molecule_ Diatomic Elements: H, N, O, F, Cl, Br, I H – H 1 molecul
