Type metal is an alloy of Pb, Sb and Sn.it consists of

Options

A. Equal amounts of the three metals
B. More amount of lead
C. More amount of antimony
D. More amount of tin

Explanation

To answer the question regarding the composition of type metal, which is an alloy of lead (Pb), antimony (Sb), and tin (Sn), we can break down the information as follows:

### Step-by-Step Solution:

1. **Understanding Type Metal Composition**:
- Type metal is an alloy primarily composed of three elements: lead (Pb), antimony (Sb), and tin (Sn).
- The typical composition of these elements in type metal varies.

2. **Lead Composition**:
- The lead (Pb) content in type metal generally ranges from 50% to 86%. This indicates that lead is the predominant element in the alloy.

3. **Antimony Composition**:
- Antimony (Sb) typically makes up about 11% to 30% of the alloy. This shows that while it is significant, it is less than the amount of lead.

4. **Tin Composition**:
- Tin (Sn) is present in the alloy in smaller amounts, usually ranging from 3% to 10%. This indicates that tin is the least abundant element in type metal.

5. **Conclusion**:
- Based on the above compositions, we can conclude that type metal does not consist of equal amounts of Pb, Sb, and Sn. Instead, it has a higher proportion of lead, followed by antimony, and the least amount of tin.

### Final Answer:
Type metal consists of more lead than antimony and tin, with the following approximate compositions:
- Lead (Pb): 50% to 86%
- Antimony (Sb): 11% to 30%
- Tin (Sn): 3% to 10%
