You read the following statement about two elements X and Y: One of the elements is a good conductor of electricity, and the other is a semiconductor. Experiments show that the first ionization energy of X is twice as great as that of Y. Which element has the greater metallic character?

Verified step by step guidance

1. Identify the properties of metals and semiconductors: Metals are typically good conductors of electricity, while semiconductors have intermediate conductivity that can be modified under certain conditions.
2. Understand the relationship between ionization energy and metallic character: Elements with lower ionization energies tend to lose electrons more easily, which is a characteristic of metals. Therefore, an element with a lower ionization energy is likely to have greater metallic character.
3. Analyze the given information: Element X has a first ionization energy that is twice as great as that of element Y. This means that element X requires more energy to remove an electron compared to element Y.
4. Determine the metallic character based on ionization energy: Since element Y has a lower ionization energy, it is more likely to lose electrons easily, indicating that it has a greater metallic character compared to element X.
5. Conclude which element has the greater metallic character: Based on the analysis, element Y, with the lower ionization energy, has the greater metallic character.
