Day 2 STAAR

The model of the periodic table below shows the locations of four elements.

A student is asked to identify an element that is a pale-yellow brittle solid and does not conduct electricity. At which location in this periodic table would the element most likely be found?

• 1
• 2
• 3
• 4

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
• all three elements are malleable and conduct electricity

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

Characteristics of a Group of Elements  
•  Is shiny
•  Is solid at room temperature
•  Has atoms with two valence electrons

Which of these elements is in this group?

• Lithium
• Strontium
• Aluminum
• Silicon

Which two elements on the periodic table are in the same period?

• Sn and Rb
• F and Cl
• K and Ba
• Se and Te

Some students conducted a laboratory investigation to learn more about the physical properties of different elements. They observed four samples and recorded their observations in the table below.

Based on these observations, which sample is most likely a nonmetal?

• Sample 1
• Sample 2
• Sample 3
• Sample 4
