When covalent bond is formed between two similar atoms, for example in `H_2, O_2, CI_2,` or `F_2`, the shared pair of electrons is equally attracted by the two atoms. As a result electrons pair is situated exactly between the two identical nuclei. The bond so formed is called

Options

A. ionic bond
B. polar covalent bond
C. non-polar covalent bond
D. None of the above

Answer

To solve the question, we need to understand the nature of the bond formed between two similar atoms in a covalent bond. Let's break it down step by step:

### Step 1: Identify the Type of Bond
When two identical atoms form a covalent bond, they share electrons equally. This is because both atoms have the same electronegativity, meaning they have the same ability to attract electrons.

**Hint:** Look for the definition of covalent bonds and how they behave between similar atoms.

### Step 2: Understand Electron Sharing
In molecules like H₂, O₂, Cl₂, or F₂, the shared pair of electrons is located exactly in the middle of the two nuclei. This equal sharing results in no partial charges developing on either atom.

**Hint:** Consider how the position of shared electrons affects the polarity of the bond.

### Step 3: Define the Bond Type
Since the electrons are shared equally, the bond formed is classified as a non-polar covalent bond. Non-polar covalent bonds occur when the electron density is evenly distributed between the two atoms.

**Hint:** Recall the characteristics of non-polar vs. polar covalent bonds.

### Step 4: Eliminate Other Options
- **Ionic Bond:** This involves the complete transfer of electrons from one atom to another, which is not the case here.
- **Polar Covalent Bond:** This occurs when there is an unequal sharing of electrons, leading to partial charges, which does not apply to identical atoms.
- **None of These:** This option can be eliminated since we have identified a valid bond type.

### Conclusion
The bond formed between two similar atoms, as described in the question, is called a **non-polar covalent bond**.

**Final Answer:** Non-polar covalent bond
