Explanation:
Characteristics of Cesium:
- Cesium is a chemical element with the symbol Cs and atomic number 55.
- It is a soft, silvery-gold alkali metal with a melting point of 28.5°C (83.3°F).
- Cesium is one of only five elements that are liquid at or near room temperature, along with mercury, francium, gallium, and bromine.
Liquid state of Cesium:
- Cesium has a melting point of approximately 28.5°C, which means it is a liquid slightly above 30°C.
- This characteristic makes cesium unique among the alkali metals, as the other alkali metals such as sodium, lithium, and potassium are solid at room temperature.
Answer to the Question:
- Based on the given information, the element which is a liquid slightly above 30°C is cesium.
- Therefore, the correct answer to the question is option B: Cesium.
