In the periodic table, bismuth belongs to which group

Options

A. Group-8
B. Group-10
C. Group-15
D. Group-12

Answer

To determine which group bismuth belongs to in the periodic table, we can follow these steps:

### Step 1: Identify the Element
Bismuth is a chemical element with the symbol **Bi** and an atomic number of **83**.

### Step 2: Determine the Electronic Configuration
The electronic configuration of bismuth is given as:
- **Xe 4f14 5d10 6s2 6p3**.

### Step 3: Identify the Block of the Element
From the electronic configuration, we can see that the outermost electrons are in the **p orbital** (6p3). This indicates that bismuth is a **p-block element**.

### Step 4: Count the Valence Electrons
For p-block elements, the number of valence electrons is determined by the electrons in the outermost p subshell. In the case of bismuth, there are **3 valence electrons** in the 6p subshell.

### Step 5: Determine the Group Number
The group number for p-block elements can be calculated using the formula:
- **Group number = Number of valence electrons + 10**.

For bismuth:
- **Group number = 3 (valence electrons) + 10 = 13**.

### Step 6: Identify the Correct Group
However, we must note that bismuth is actually in Group 15 of the periodic table, which corresponds to the p-block elements that have 5 valence electrons. The confusion arises because the formula used applies to the entire p-block, but bismuth specifically has 5 valence electrons (3 from the p orbital and 2 from the s orbital).

### Conclusion
Thus, bismuth belongs to **Group 15** of the periodic table.

### Final Answer
Bismuth belongs to **Group 15** of the periodic table.
