Q: Which of the following is the heaviest alkali metal?
Solution: Cesium (Cs) is the heaviest alkali metal.
Steps: 5
Step 1: Understand what alkali metals are. Alkali metals are a group of elements in the periodic table that are found in Group 1.
Step 2: Identify the alkali metals. The alkali metals include Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr).
Step 3: Look at the atomic weights of the alkali metals. The atomic weights are approximately: Li (6.94), Na (22.99), K (39.10), Rb (85.47), Cs (132.91), and Fr (223).
Step 4: Compare the atomic weights. The heaviest alkali metal is the one with the highest atomic weight.
Step 5: Determine which alkali metal has the highest atomic weight. Cesium (Cs) has the highest atomic weight at approximately 132.91.
