Name the element having the lowest electronegative, lightest and liquid metal.

Explanation

To solve the question, we need to identify three specific elements based on the criteria given: the element with the lowest electronegativity, the lightest metal, and the liquid metal.

### Step-by-Step Solution:

1. **Identify the Element with the Lowest Electronegativity:**
- Electronegativity is a measure of an atom's ability to attract and hold onto electrons. In the periodic table, electronegativity generally increases from left to right across a period and decreases from top to bottom within a group.
- The element with the lowest electronegativity is found in Group 1 (alkali metals), specifically at the bottom of the group.
- **Answer:** Cesium (Cs) has the lowest electronegativity.

2. **Identify the Lightest Metal:**
- The lightest metal can be determined by looking at the atomic masses of the metals in the periodic table.
- Among all the metals, lithium (Li) has the lowest atomic mass.
- **Answer:** Lithium (Li) is the lightest metal.

3. **Identify the Liquid Metal:**
- Most metals are solid at room temperature, but there are exceptions. The only metal that is liquid at room temperature is found in Group 1.
- Cesium (Cs) is one of the alkali metals that becomes liquid just above room temperature.
- **Answer:** Cesium (Cs) is also the liquid metal.

### Final Answers:
- Lowest Electronegativity: **Cesium (Cs)**
- Lightest Metal: **Lithium (Li)**
- Liquid Metal: **Cesium (Cs)**
