Question

All metals exist as solid at room temperature except the metal &#8216;X&#8217;. Name the metal &#8220;X&#8217;.a)Tungstenb)Mercuryc)Goldd)PotassiumCorrect answer is option 'B'. Can you explain this answer?

Answer

Mercury is liquid at room temperature because it has a low boiling point . It cannot form diatomic mercury molecules in gas phase, so it is not a gas. In room temperature, mercury melts and changes from it's solid state to liquid state.

Answer

Mercury because it has low melting point

Answer

It is the only metal that is liquid at room temperature. It has the lowest melting point and boiling point of any other metal. It has low thermal conductivity, and a quite low electrical conductivity. It is the only metal that doesn’t form diatomic molecules in the gaseous phase.

Answer

The metal 'X' is mercury, that's for sure,but don't know why,my teacher never told that.

Answer

Answer:

The metal X that exists as a liquid at room temperature is mercury. Here is an explanation of why mercury is the correct answer:

1. Definition of Room Temperature:
Room temperature is typically defined as the average temperature range between 20°C (68°F) and 25°C (77°F). At this temperature range, most metals are in their solid state.

2. Metals:
Metals are elements that have high electrical conductivity, luster, and malleability. They are usually solid at room temperature due to the strong metallic bonds between their atoms.

3. Exceptions to the Rule:
While most metals are solid at room temperature, there are a few exceptions. These exceptions include mercury (Hg) and gallium (Ga), which exist as liquids. However, among these two exceptions, only mercury is the correct answer for this question.

4. Properties of Mercury:
Mercury is a unique metal with several distinct properties that contribute to its liquid state at room temperature:
- Low Melting Point: Mercury has a very low melting point of -38.83°C (-37.89°F). This low melting point allows it to remain in a liquid state within the typical room temperature range.
- Weak Metallic Bonds: The metallic bonds in mercury are relatively weak compared to other metals. This is primarily due to the presence of unpaired electrons in its outermost electron shell. The weak metallic bonds contribute to its lower melting point and liquid state.
- Density: Mercury is a dense liquid, with a density of 13.534 g/cm³ at room temperature. This high density allows it to flow freely and gives it a unique appearance.

Conclusion:
In conclusion, the metal X that exists as a liquid at room temperature is mercury (Hg). Its low melting point, weak metallic bonds, and high density contribute to its liquid state. The other options (tungsten, gold, and potassium) are all metals that exist as solids at room temperature.
