If an element X is placed in group 14, the formula its chloride is:

Explanation

To determine the formula of the chloride of an element X that is placed in Group 14, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Group**:
- Element X is in Group 14 of the periodic table. Elements in this group include Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), and Lead (Pb).

2. **Determine the Valence Electrons**:
- Elements in Group 14 have 4 valence electrons in their outermost shell. This is crucial for understanding how they bond with other elements.

3. **Understand Chlorine's Valence Electrons**:
- Chlorine (Cl) is in Group 17 and has 7 valence electrons. It typically needs 1 more electron to achieve a stable octet configuration.

4. **Bonding Behavior**:
- Since element X has 4 valence electrons, it can share these electrons with 4 chlorine atoms. Each chlorine atom can share 1 electron.

5. **Formulate the Compound**:
- By sharing 4 electrons with 4 chlorine atoms, the resulting compound will have the formula XCl4. This indicates that one atom of element X is bonded to four atoms of chlorine.

6. **Type of Bonding**:
- The bonding that occurs here is covalent bonding, where electrons are shared between the atoms rather than transferred.

### Final Answer:
The formula for the chloride of element X in Group 14 is **XCl4**.
