Periodic Table Map: Draw a “map” of the periodic table showing where different types of elements are found and indicate trends in properties and mass.
 * Draw the shape of the table.
 * Label the different areas of the table.
 * Explain trends in properties and mass.
 * Use colors, arrows, circled areas, and text-boxes.

The answers to the following questions should be on your map:

What types of elements are found in different areas of the periodic table? How do the properties of the elements change going across a period? Where are the least reactive metals be found? Where are the extremely reactive metals be found? Where are the moderately reactive metals be found? Where are the elements that don’t react found? Where are the extremely reactive non-metals be found? Where are the moderately reactive non-metals be found? Where are the Semimetals be found? Opposite properties: Areas of malleable vs. brittle Opposite properties: Good conductor vs. insulator What are the rows and columns called? How do number of protons and mass change going across a period? How are periods and electron energy levels related?

Patterns and Trends of the Periodic Table.

Mendeleev discovered a set of patterns that applies to all the elements. Mendeleev knew that some elements have similar chemical and physical properties. Mendeleev thought these similarities were important clues to a hidden pattern of elemental properties. Because of this, Mendeleev noticed that a pattern of properties appeared when he arranged the elements in order of increasing atomic mass. Mendeleev used this repeating pattern of properties to organize a table of the elements.

Mendeleev used the pattern he saw when he put the elements in the order of increasing mass from left to right to make his table. The repeated pattern he saw going left to right was as follows: very-reactive metals, moderately-reactive metals, less-reactive metals, semimetals, moderately-reactive nonmetals, very-reactive nonmetals, and non-reactive gases. To make his table, Mendeleev kept the elements in the order of increasing atomic mass, while making columns of elements with similar properties. This means that atomic mass increased from left to right and from top to bottom. And, each column contains elements with similar characteristics, so each column is called a family or group. Arranging elements in this way produces a table with each row having the pattern listed above and similar elements grouped in columns.

Arranging the elements by increasing mass and similar properties produced a table with rows and columns. Each row repeats the basic pattern of metals, semimetals, nonmetals, and inert gases. Each instance of this pattern in a row is called a period. Today we know that each element going across a period has one additional proton and electron. Today we also know that electron levels are being filled up going across a period. At the end of each period is an inert gas that has all its electron-energy-levels completely full. Due to this elements in the same column have the same number of outer electrons. Likewise elements in columns have their outer electron-energy-levels filled similarly. This is why elements in columns have similar physical and chemical properties.
