At which location in the periodic table would the most active metallic element be found?

• A. Upper right corner
• B. Lower left corner
• C. Lower right corner
• D. Upper left corner

Answer: (B)

Verified step by step guidance

1. Understand that the activity of metallic elements generally increases as you move down a group (column) in the periodic table because atoms have more electron shells, making it easier to lose electrons and react.
2. Recognize that metallic character increases as you move from right to left across a period (row) because elements on the left side tend to lose electrons more readily, which is a characteristic of metals.
3. Combine these trends: the most active metals are found where metallic character is highest, which is at the bottom of the groups on the left side of the periodic table.
4. Identify that the lower left corner of the periodic table contains the alkali metals, such as cesium and francium, which are known to be the most reactive metals.
5. Conclude that the most active metallic element would be found in the lower left corner of the periodic table.
