The bond between hydrogen and chlorine would be

Options

A. not formed
B. ionic
C. polar covalent
D. non-polar covalent

Explanation

To determine the type of bond between hydrogen and chlorine, we can follow these steps:

### Step 1: Identify the Elements and Their Valence Electrons
- **Hydrogen (H)** has 1 electron in its outer shell.
- **Chlorine (Cl)** has an atomic number of 17, and its electronic configuration is 2, 8, 7. Therefore, it has 7 valence electrons.

**Hint:** Remember that the number of valence electrons determines how an atom will bond with others.

### Step 2: Determine the Need for Bonding
- Hydrogen needs 1 more electron to complete its outer shell (to achieve a stable configuration like helium).
- Chlorine needs 1 more electron to complete its outer shell (to achieve a stable configuration like argon).

**Hint:** Atoms tend to bond in order to achieve a full outer shell, which is often referred to as the octet rule.

### Step 3: Type of Bond Formation
- Since both hydrogen and chlorine need to share electrons to achieve full outer shells, they will form a covalent bond.
- In this case, hydrogen will share its single electron with chlorine.

**Hint:** Covalent bonds are formed when atoms share electrons to fill their outer shells.

### Step 4: Electronegativity Consideration
- The electronegativity of hydrogen is approximately 2.1, while that of chlorine is about 3.5.
- Chlorine is more electronegative than hydrogen, meaning it will attract the shared electron more strongly.

**Hint:** Electronegativity differences can indicate the polarity of the bond formed between two atoms.

### Step 5: Determine the Polarity of the Bond
- Due to the difference in electronegativity, the shared electron will spend more time closer to chlorine, resulting in a partial negative charge (δ-) on chlorine and a partial positive charge (δ+) on hydrogen.
- This results in a polar covalent bond.

**Hint:** A polar covalent bond occurs when there is an unequal sharing of electrons due to differences in electronegativity.

### Final Answer
The bond between hydrogen and chlorine is a **polar covalent bond**.
