For an element with configuration `5s^(2)4d^(10)5p^(3)` the chemistry is likely to be similar to that of

Options

A. boron
B. oxygen
C. chlorine
D. phosphours

Explanation

To determine which element has similar chemistry to the element with the electron configuration \(5s^2 4d^{10} 5p^3\), we need to identify the group of the element based on its electron configuration and then find another element in the same group.

### Step-by-Step Solution:

1. **Identify the Element**:
- The given electron configuration is \(5s^2 4d^{10} 5p^3\).
- The total number of electrons can be calculated as follows:
- \(5s^2\) contributes 2 electrons,
- \(4d^{10}\) contributes 10 electrons,
- \(5p^3\) contributes 3 electrons.
- Therefore, the total number of electrons is \(2 + 10 + 3 = 15\).
- This corresponds to the atomic number 51, which is the element Antimony (Sb).

2. **Determine the Group**:
- Antimony (Sb) is located in Group 15 of the periodic table (also known as Group V or the nitrogen group).
- Elements in the same group typically exhibit similar chemical properties due to their similar valence electron configurations.

3. **Find Similar Elements**:
- To find an element with similar chemistry, we need to look for other elements in Group 15.
- The elements in Group 15 include:
- Nitrogen (N)
- Phosphorus (P)
- Arsenic (As)
- Antimony (Sb)
- Bismuth (Bi)

4. **Choose the Most Similar Element**:
- Among these, Arsenic (As) is the closest in terms of atomic number and properties to Antimony (Sb).
- Both elements have similar valence electron configurations, which leads to similar chemical behavior.

5. **Conclusion**:
- Therefore, the chemistry of the element with the configuration \(5s^2 4d^{10} 5p^3\) (Antimony) is likely to be similar to that of Arsenic (As).

### Final Answer:
The chemistry is likely to be similar to that of Arsenic (As).
