| Goal
I. Understand the classification of matter. |
Objectives: To meet the requirements of Goal
I, you must be able to:
-
distinguish between:
physical/chemical changes AND physical/chemical
properties
of matter;
-
define matter,
state
of matter, phase; list three states of matter; recognize
that changes in state are physical changes;
-
define substance;
categorize a given substance as an element or compound based on
the chemical formula for the substance;
-
distinguish between:
-
element, compound and
mixture;
-
heterogeneous and homogenous
mixtures;
-
state the law
of constant composition. [Top]
| Goal II. Understand the
distinguishing characteristics of atoms, molecules and ions. |
Objectives: To meet the requirements of Goal
II, you must be able to:
-
describe the model
of the atom:
- knowing the contributions of Thompson, Rutherford and Millikan,
-
giving the charge and location
of protons and electrons within the atom
-
equating and element's atomic
number to the number of protons in its nucleus,
-
relating the number of
protons (atomic number) with the identity of the element,
-
equating the number of protons
to the number of electrons in an electrically neutral atom;
-
describe the model
of the atom:
-
define group (family) and period
-
identify an element as a metal, nonmetal or metalloid
-
write the names and symbols of alkali metals, alkaline
earth metals, halogens and noble (inert) gases,
-
recognize transition elements, inner transition elements
and main group elements by both name and symbol
- predict the charge
on an ion formed from a given element;
- determine the number
of protons and electrons in a given ion. [Top]
| Goal III. Write and interpret
chemical formulas and reactions. |
- recognize and balance
equations for simple chemical changes (reactions) ;
- distinguish among
chemical formulas for molecules, ions, monatomic ions, polyatomic
ions, cations and anions;
- interpret the formula
for a compound or an element:
in terms of numbers of atoms in its molecules
as representing a molecular compound or an ionic compound
- know that the following
elements exist under normal conditions as diatomic molecules: H2,
N2, O2, F2, Cl2, and I2;
- explain the terms
reactants
and products, and interpret the symbols used in writing a chemical
equation;
- write formulas for
ionic
compounds;
- write and balance
simple chemical equations. [Top]
