Which of the following elements is not an alkali metal? (2023)
Step 1: Understand what alkali metals are. Alkali metals are elements found in Group 1 of the periodic table. They include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Step 2: Identify the elements listed in the question. Look for the element that is not in Group 1.
Step 3: Check the element aluminum (Al). Aluminum is found in Group 13 of the periodic table, not Group 1.
Step 4: Conclude that since aluminum (Al) is not in Group 1, it is not an alkali metal.
