In Mendeleev's periodic table, gaps were left for the elements to be discovered later. Which of the following elements found a place in the periodic table later ?

Options

A. Germanium
B. Chlorine
C. Oxygen
D. Silicon

Explanation

To solve the question regarding which element found a place in Mendeleev's periodic table later, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Mendeleev's Periodic Table**: Mendeleev created his periodic table based on atomic mass and properties of elements. He left gaps for elements that had not yet been discovered at the time.

2. **Identify Elements Discovered Later**: After Mendeleev's periodic table was published, several elements were discovered. Notably, scandium, gallium, and germanium were identified after the table was created.

3. **Check the Options Provided**: The question likely provides multiple-choice options. Among these, we need to identify which of the elements (scandium, gallium, germanium) was not included in Mendeleev's original table.

4. **Determine the Correct Answer**:
- **Scandium** was discovered in 1879, which is after Mendeleev published his table in 1869.
- **Gallium** was discovered in 1875, also after the table was published.
- **Germanium** was discovered in 1886, which is the latest among the three.

Since the question asks for an element that found a place in the periodic table later, the correct answer is **germanium**.

### Final Answer:
**Germanium** is the element that found a place in Mendeleev's periodic table later.
