Which of the following is the artificial element in the periodic table ?

Options

A. Tc
B. Te
C. Ru
D. Os

Explanation

To determine which of the following is the artificial element in the periodic table, we can follow these steps:

### Step 1: Understand the Definition of Artificial Elements
Artificial elements are those that are not found naturally on Earth and are typically created in laboratories or through nuclear reactions. They have atomic numbers greater than 92 (the atomic number of Uranium), as elements beyond this point are generally unstable and do not occur naturally.

### Step 2: Identify the Given Options
Since the question does not provide specific options, we will consider common artificial elements known in the periodic table, such as Technetium (Tc), Promethium (Pm), and others.

### Step 3: Research the Elements
- **Technetium (Tc)**: Atomic number 43, discovered in 1937, and is the first artificially produced element.
- **Promethium (Pm)**: Atomic number 61, also an artificial element, discovered in 1945.
- Other elements like Plutonium (Pu) and Neptunium (Np) are also artificial but were discovered later.

### Step 4: Conclude the Correct Answer
From the research, Technetium (Tc) is the first artificial element that was created and is recognized in the periodic table. Therefore, if Technetium is one of the options, it would be the correct answer.

### Final Answer
The artificial element in the periodic table is Technetium (Tc).
