Which of the following element of Group VA is more metallic

Options

A. Bi
B. As
C. Sb
D. P

Answer

To determine which element of Group VA (or Group 15) is more metallic among bismuth, arsenic, antimony, and phosphorus, we can follow these steps:

### Step 1: Identify the Elements in Group VA
Group VA (or Group 15) of the periodic table includes the following elements:
- Nitrogen (N)
- Phosphorus (P)
- Arsenic (As)
- Antimony (Sb)
- Bismuth (Bi)

### Step 2: Understand the Trend in Metallic Character
Metallic character generally increases as you move down a group in the periodic table. This is due to the increase in atomic size and the decrease in ionization energy, which makes it easier for an atom to lose electrons and exhibit metallic properties.

### Step 3: Classify the Elements
- **Nitrogen (N)**: Nonmetal
- **Phosphorus (P)**: Nonmetal
- **Arsenic (As)**: Metalloid
- **Antimony (Sb)**: Metalloid
- **Bismuth (Bi)**: Metal

### Step 4: Compare the Elements
As we move down the group from nitrogen to bismuth:
- Nitrogen and phosphorus are nonmetals.
- Arsenic and antimony are metalloids, which have properties of both metals and nonmetals.
- Bismuth is a metal.

### Step 5: Conclusion
Since metallic character increases down the group, and among the given options, bismuth is the only metal, it is the most metallic element in Group VA.

### Final Answer
**Bismuth (Bi) is the most metallic element among the options provided.**
