TBT Vocabulary practicce periodic table

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

• nonmetals
• metalloids
• noble gases
• metals

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

• nonmetals
• metalloids
• groups

• metals

NGSS.MS-PS1-1

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

• nonmetals
• metalloids
• groups

• metals

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

• periods
• classes

• isotopes
• groups or families

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

• periods

• groups

• classes

• families

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

• Alkali metals

• Halogens

• noble gases
• Transition Metals

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

• Halogens

• Noble Gases

• Metalloids

• Alkali Metals

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

• Noble Gases

• Halogens

• Transition Metals

• Alkali Metals

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

• transition metals

• halogens

• noble gases

• Alkali metals
