Most of the elements that touch the zigzag line belong to one major group. What is that group?

• Metals
• Metalloids
• Nonmetals
• Gases

What kinds of properties do metalloids have elements tend to have?

• Metalloids can be shiny or dull, malleable, ductile, brittle, and conduct electricity.
• Metalloids have luster, are malleable, ductile and good conductors of heat and electricity.
• Metalloids have not luster, are brittle, not ductile, not malleable and poor conductors of electricity.

Locate the box in Group 18 in the fourth period. Predict the state of matter and the chemical reactivity of the element that belongs in that box.

• The element is a gas, one of the halogen gases. It does not ordinarily react with other elements to form compounds.
• The element is a gas, one of the noble gases. It does ordinarily react with other elements to form compounds.
• The element is a gas, one of the noble gases. It does not ordinarily react with other elements to form compounds.
• The element is a gas, hydrogen gas. It does ordinarily react with other elements to form compounds.

Explain why iron and certain other transition metals are used in construction instead of the alkali metals.

• When people build a structure, they want it to be stable, to support great weight, and to last for a long time. Iron and certain other transition metals have these characteristics. Alkali metals, on the other hand, are soft and highly reactive, so they are not useful for construction.
• When people build a structure, they want it to be stable, to support great weight, and to last for a short time. Iron and certain other transition metals do not have these characteristics. Alkali metals, on the other hand, are hard and highly reactive, so they are useful for construction.

Compare the properties of metals and nonmetals.

• Nonmetals are generally solid at room temperature; are shiny, malleable, and ductile; and are good conductors. Metals are generally gases at room temperature. Solid nonmetals are usually dull and brittle, and are poor conductors. The properties of metals are generally the same of the properties of nonmetals.
• Metals are generally liquid at room temperature; are shiny, malleable, and ductile; and are good conductors. Nonmetals are generally gases at room temperature. Solid nonmetals are usually shiny and strong, and are poor conductors. The properties of metals are generally the opposite of the properties of nonmetals.
