Periodic Table Vocab

1) elements in Groups 3–12 of the periodic table, which often have more than one valence electron configuration resulting in different chemical bonds

• Transition Metals
• Metals
• Nonmetals
• Metalloids
• Groups

2) elements that are typically dense, solid, ductile, malleable, highly conductive, and chemically reactive; located on the left side of the periodic table

• Metals
• Nonmetals
• Metalloids
• Groups
• Periods

3) gaseous chemical elements that do not easily combine with other elements because they contain valence shells that are complete

• Noble Gases
• Metals
• Nonmetals
• Metalloids
• Groups

4) elements that have properties between the metals and nonmetals; they are all solids at room temperature; they can act as electrical conductors under the right conditions

• Metalloids
• Metals
• Nonmetals
• Groups
• Periods

5) the grouping of elements with similar characteristics on the periodic table into 3 major categories known as metals, nonmetals, and metalloids

• Classes
• Metals
• Nonmetals
• Metalloids
• Groups

6) elements that typically have four or more valence electrons; they are usually dull, brittle, and poor conductors of heat and electricity

• Nonmetals
• Metals
• Metalloids
• Groups
• Periods

7) horizontal rows on the periodic table that contain atoms having the same number of electron energy levels

• Periods
• Metals
• Nonmetals
• Metalloids
• Groups

8) elements in Group 17 of the periodic table that have seven valence electrons; they are nonmetals that are highly reactive

• Halogens
• Metals
• Nonmetals
• Metalloids
• Groups

9) elements in Group 1 of the periodic table, having one valence electron that they can easily lose, making them the most reactive of all the metals

• Alkali Metals
• Metals
• Nonmetals
• Metalloids
• Groups

10) vertical columns on the periodic table that contain atoms that generally have the same number of valence electrons, giving them similar chemical properties

• Groups
• Metals
• Nonmetals
• Metalloids
• Periods
