Options

A. `[Xe] 4f^(14) 5d^(10)6p^(1-6)`
B. `[Xe]5f^(14)6d^(10) 6p^(1-6)`
C. `[Kr] 5f^(14) 5d^(10) 6p^(1-6)`
D. `[Xe]4f^(0) 5d^(10)6p^(1-6)`

Answer

To determine the p-block elements of the sixth period, we need to identify the elements that fall under this category and their electronic configurations. Here’s a step-by-step solution:

### Step 1: Identify the Period
The sixth period of the periodic table includes elements from atomic number 55 (Cesium, Cs) to atomic number 86 (Radon, Rn).

### Step 2: Identify the p-block Elements
The p-block elements in the sixth period are:
- Thallium (Tl, atomic number 81)
- Lead (Pb, atomic number 82)
- Bismuth (Bi, atomic number 83)
- Polonium (Po, atomic number 84)
- Astatine (At, atomic number 85)
- Radon (Rn, atomic number 86)

### Step 3: Write the General Electronic Configuration
The general electronic configuration for the p-block elements in the sixth period can be expressed as:
- The core configuration is based on the nearest noble gas, which is Xenon (Xe).
- The additional electrons fill the 4f, 5d, and 6p orbitals.

Thus, the electronic configuration for these elements can be represented as:
\[ \text{[Xe]} 4f^{14} 5d^{10} 6p^{1-6} \]
Where:
- 6p can hold up to 6 electrons (from 1 to 6).

### Step 4: Conclusion
The p-block elements of the sixth period are Thallium (Tl), Lead (Pb), Bismuth (Bi), Polonium (Po), Astatine (At), and Radon (Rn), with the general electronic configuration being \[ \text{[Xe]} 4f^{14} 5d^{10} 6p^{1-6} \].
