Question

Identify the elements \(x\) and \(z\) in the following representation. (Sb = antimony)

• A. Ge, Po
• B. Sn, Ga
• C. Ga, Bi
• D. Si, Te

Hint:

In the periodic table: \[ \text{Horizontal movement} \rightarrow \text{change in group} \] \[ \text{Vertical movement} \rightarrow \text{change in period} \] Use the group and period positions carefully to identify neighboring elements.

Answer 1

The Correct Option is A

Step 1: Locate antimony in the periodic table.
Antimony (Sb) belongs to: \[ \text{Group }15 \] and \[ \text{Period }5 \]

Step 2: Identify the position of \(x\).
In the figure, \(x\) is placed diagonally above and left of Sb.
That means: One period above and one group left Moving one group left from Group \(15\): \[ \text{Group }14 \] Moving one period above Period \(5\): \[ \text{Period }4 \] The element in Group \(14\), Period \(4\) is: Ge (Germanium) Thus, \[ x=\text{Ge} \]

Step 3: Identify the position of \(z\).
The element \(z\) is diagonally below and right of Sb.
That means: One period below and one group right Moving one group right from Group \(15\): \[ \text{Group }16 \] Moving one period below Period \(5\): \[ \text{Period }6 \] The element in Group \(16\), Period \(6\) is: Po (Polonium) Thus, \[ z=\text{Po} \]

Step 4: Final conclusion.
Therefore, \[ \boxed{x=\text{Ge},\quad z=\text{Po}} \] Hence, the correct option is \[ \boxed{(1)} \]
