Examine the periodic table of the elements and identify which groups of elements are metals and which are nonmetals.

Metals and nonmetals are scattered throughout the table

Metals are found to the right of the zig-zag line; nonmetals to the left

Metals are found in groups 3B-2B; nonmetals are found in the remaining groups

Metals are found to the left of the zig-zag line; non metals to the right.

is a measure of the attraction of an atom for electrons in a chemical bond. Elements with higher electronegativity values are more reactive. Whether an ionic bond forms or does not form is determined by taking the between the electronegativities of two atoms. If the difference is equal to or greater than , an ionic bond will form.

Which of the following explanations best describes the process by which the elements calcium and oxygen combine to form the binary compound calcium oxide?
2Ca_(s) + O_2(g) -> 2CaO_(s)

Calcium has a low electronegativity, so it loses electrons, resulting in a positively charged ion. Oxygen has a high electronegativity, so it gains electrons, resulting in a negatively charged oxide ion. The oppositely charged ions are attracted to each other, forming calcium oxide.
