Where are the metalloids located on the periodic table?

• A. Along the staircase line between metals and nonmetals
• B. In the far right column, among the noble gases
• C. In the bottom two rows, known as the lanthanides and actinides
• D. In the far left column of the periodic table

Answer: (A)

Verified step by step guidance

1. Understand that the periodic table is divided into metals, nonmetals, and metalloids based on their properties.
2. Recall that metalloids have properties intermediate between metals and nonmetals, so they are located between these two groups on the periodic table.
3. Identify the 'staircase' or zigzag line on the periodic table, which separates metals on the left from nonmetals on the right.
4. Recognize that metalloids are found along this staircase line, acting as a boundary between metals and nonmetals.
5. Confirm that the other options (far right column for noble gases, bottom two rows for lanthanides and actinides, far left column for alkali metals) do not correspond to the location of metalloids.
