Answer 1

To determine which two elements most likely have similar properties, we can look at their positions in the periodic table.

- **F (Fluorine)** and **Ne (Neon)**: These elements are in different groups; Fluorine is a halogen (Group 17) and Neon is a noble gas (Group 18).

- **Cs (Cesium)** and **Rn (Radon)**: Cesium is an alkali metal (Group 1) and Radon is a noble gas (Group 18).

- **Ca (Calcium)** and **Sc (Scandium)**: Calcium is an alkaline earth metal (Group 2), while Scandium is a transition metal (Group 3).

- **Li (Lithium)** and **Fr (Francium)**: Both are alkali metals and belong to Group 1 of the periodic table.

Given this analysis, the best answer is:

**Li and Fr**, as both belong to the same group (alkali metals) and are likely to have similar properties.
