Multiple Select

Which of the following are uses of silicon and germanium as mentioned in the lesson?

• Computer chips

• Solar cells

• Batteries

• Plastic production

Multiple Choice

Which of the following statements best describes metalloids?

• They have properties of both metals and nonmetals.

• They are only metals.

• They are only nonmetals.

• They are gases at room temperature.

Multiple Choice

What is the main difference between the modern periodic table and the expanded periodic table as shown in the images?

• The expanded table includes the lanthanide and actinide series separately.

• The modern table has more elements.

• The expanded table does not show transition elements.

• The modern table is arranged by atomic mass.

Open Ended

Explain how the group number and period number help in organizing the elements in the periodic table.

Multiple Choice

How many distinct blocks is the periodic table divided into based on energy sublevels?

• 2

• 3

• 4

• 5

Multiple Choice

Why is there no p-block element in period 1 of the periodic table?

• Because the p sublevel does not exist for the first principal energy level (n=1).

• Because period 1 contains only transition metals.

• Because the p-block elements are only found in periods 2 and above due to their atomic size.

• Because period 1 contains only noble gases.

Multiple Choice

Which of the following statements best explains why the s-block spans two groups in the periodic table?

• Because the s orbitals hold two electrons at the most, the s-block spans two groups.

• Because the s-block contains only metals.

• Because the s-block elements have partially filled p orbitals.

• Because the s-block elements are transition metals.

Open Ended
