Which of the following elements has the highest melting point among the alkali metals? (2023)

Step 1: Understand what alkali metals are. Alkali metals are found in Group 1 of the periodic table and include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Step 2: Know that melting point is the temperature at which a solid becomes a liquid.
Step 3: Recognize that among the alkali metals, lithium is the first element in the group.
Step 4: Remember that smaller atoms generally have stronger metallic bonds, which can lead to higher melting points.
Step 5: Compare the melting points of the alkali metals: Lithium has a melting point of about 180.5°C, while the others have lower melting points.
Step 6: Conclude that lithium (Li) has the highest melting point among the alkali metals.
