Answer 1

The correct answer is option 3.

Key Points

Element 'X' belongs to a period with n = 4, indicating it is in the 4th period of the periodic table.
Element 'Y' belongs to a period with n = 2, indicating it is in the 2nd period of the periodic table.
Both elements belong to the same group, meaning they have similar chemical properties but different energy levels.
In a given group, the metallic character increases as you move down the group.
Therefore, element 'X' is more metallic than element 'Y' as it is located further down the group compared to element 'Y'.

Additional Information

Periodic Trends
- Across a period, from left to right, the metallic character decreases.
- Down a group, the metallic character increases.
Metallic Character
- Elements with higher metallic character tend to lose electrons more easily and exhibit properties such as malleability and electrical conductivity.
Group Properties
- Elements in the same group have similar valence electron configurations, leading to similar chemical behavior.
- However, the physical properties such as metallic character can vary significantly within the group.
