Solution

Cesium is the element that is a liquid above 303 Kelvin. Here are the steps to answer this question:

  1. Understand the question: The question is asking for an element that is in a liquid state above 303 Kelvin.

  2. Know the melting points of the given elements: The melting points of the elements in Kelvin are as follows: Cesium = 301.7K, Lithium = 453.65K, Sodium = 370.87K, Magnesium = 923K.

  3. Compare the melting points with 303 Kelvin: Only Cesium has a melting point lower than 303 Kelvin, which means it will be in a liquid state above this temperature.

So, the answer is Cesium.
