Groups and Periods
On the periodic table,
• elements are arranged according to similar properties.
• groups contain elements with similar properties in vertical columns.
• periods are horizontal rows of elements.

Group Numbers
Group Numbers
• use the letter A for the main elements (1A to 8A) and the letter B for the transition elements.
• Or: use numbers 1-18 to the columns from left to right.

Metals
• are shiny and ductile.
• are good conductors of heat and electricity.
Nonmetals
• are dull, brittle, and poor conductors.
• are good insulators.
Metalloids
• are better conductors than nonmetals, but not as good as metals.
• are used as semiconductors and insulators.
