METALS, NONMETALS, and METALLOIDS

1. Aluminum, sulfur, and chlorine are elements found on the periodic table. Tests involving these three elements would show that at normal room temperature--

• Sulfur is malleable and aluminum conducts electricity

• Chlorine is malleable and conducts electricity

• Aluminum is malleable and conducts electricity

• DAll three elements are malleable and conduct electricity

2. Which statement does NOT correctly compare silicon with another element?

• Silicon is a better conductor of electricity than sulfur.

• Silicon conducts electricity as well as copper does.

• Silicon is a solid at room temperature, but argon is a gas.

• Silicon is less malleable than silver.

An element has a metallic-gray appearance. It also has the properties of both a metal and a nonmetal. n which section of the periodic table indicated above would the element most likely be found?

• 1

• 2

• 3

• 4

The periodic table is organized into groups and periods of elements. The characteristics of a certain group of group of elements are listed below.

Which of these elements is in this group?

• Lithium

• Strontium

• Aluminum

• Silicon

Element R and Element Q have the same number of valence electrons. These elements both have similar chemical behavior, but Element R has fewer energy levels than Element Q.

Which statement best describes the positions of the two elements in the periodic table?

• The two elements are in the same period, with Element R the first element in the period and Element Q the last element.

• The two elements are side by side in the same period, with Element Q to the left of Element R.

• The two elements are in the same group, with Element R just above Element Q.

• The two elements are in the same group, with Element Q at the top of the group and Element R at the bottom.
