The elements in the periodic table are arranged in vertical columns called (1)____________________. Metals are on the (2)____________________ and lower sides of the periodic table. Nonmetals are on the right and (3)____________________ sides.

Every substance is either an element or a (4)____________________. A compound is either (5)____________________ or ionic in nature. Molecular compounds are composed of two or more (6)____________________. The representative particle of a molecular compound is a (7)____________________. Ionic compounds are composed of oppositely charged (8)____________________ combined in electrically neutral groupings. The charges of the ions of most elements in groups 1, 2, and 13-17 can be determined by the position of these elements in the periodic table. Most (9)____________________ metals have more than one common ionic charge. Binary ionic compounds are named by writing the name of the (10)____________________ followed by the name of the (11)____________________. Names of binary compounds end in (12)____________________. For example, NaI is (13)____________________.

According to the stock method of naming, when a cation has more than one ionic charge, a (14)____________________ is used in the name.

Ternary ionic compounds contain at least one (15)____________________ ion.

Binary molecular compounds are composed of two (16)____________________ elements. The name of this type of compound ends in (17)____________________. Prefixes are used to show how many (18)____________________ of each element are present in a molecule of the compound. For example, As2S5 is (19)____________________.

True/False: Classify each of these statements as true or false.

_______ 20. An anion is any atom or groups of atoms with a positive charge.
