To determine which two elements most likely have similar properties, we can look at their positions in the periodic table. Elements in the same group (column) generally exhibit similar chemical properties.

  1. Cs and Rn: Cesium (Cs) is an alkali metal (Group 1), while Radon (Rn) is a noble gas (Group 18). They do not share similar properties.

  2. Ca and Sc: Calcium (Ca) is an alkaline earth metal (Group 2), and Scandium (Sc) is a transition metal (Group 3). They are not in the same group and do not share strong similarities.

  3. Li and Fr: Lithium (Li) is also an alkali metal (Group 1), and Francium (Fr) is another alkali metal found in the same group. They have similar properties.

  4. F and Ne: Fluorine (F) is a halogen (Group 17), and Neon (Ne) is a noble gas (Group 18). They do not share similar properties.

Based on this analysis, the two elements that most likely have similar properties are Li and Fr (Lithium and Francium).
