Sure! Let's go through the given list of chlorides and determine whether they are ionic or covalent.

Ionic Compounds:
Ionic compounds are usually formed when a metal reacts with a non-metal. Metals tend to lose electrons and form positively charged ions (cations), while non-metals tend to gain electrons and form negatively charged ions (anions).

Covalent Compounds:
Covalent compounds are typically formed between non-metals by sharing electrons.

Here’s the detailed classification:

1. KCl (Potassium chloride)
- Type: Ionic
- Reason: Potassium (K) is a metal and Chlorine (Cl) is a non-metal.

2. NCl₃ (Nitrogen trichloride)
- Type: Covalent
- Reason: Both Nitrogen (N) and Chlorine (Cl) are non-metals.

3. ICl (Iodine monochloride)
- Type: Covalent
- Reason: Both Iodine (I) and Chlorine (Cl) are non-metals.

4. MgCl₂ (Magnesium chloride)
- Type: Ionic
- Reason: Magnesium (Mg) is a metal and Chlorine (Cl) is a non-metal.

5. PCl₅ (Phosphorus pentachloride)
- Type: Covalent
- Reason: Both Phosphorus (P) and Chlorine (Cl) are non-metals.

6. SiCl₄ (Silicon tetrachloride)
- Type: Covalent
- Reason: Both Silicon (Si) and Chlorine (Cl) are non-metals.

7. PCl₃ (Phosphorus trichloride)
- Type: Covalent
- Reason: Both Phosphorus (P) and Chlorine (Cl) are non-metals.

8. CaCl₂ (Calcium chloride)
- Type: Ionic
- Reason: Calcium (Ca) is a metal and Chlorine (Cl) is a non-metal.

9. CsCl (Cesium chloride)
- Type: Ionic
- Reason: Cesium (Cs) is a metal and Chlorine (Cl) is a non-metal.

10. CuCl₂ (Copper(II) chloride)
- Type: Ionic
- Reason: Copper (Cu) is a metal and Chlorine (Cl) is a non-metal.

11. CrCl₃ (Chromium(III) chloride)
- Type: Ionic
- Reason: Chromium (Cr) is a metal and Chlorine (Cl) is a non-metal.

12. CCl₄ (Carbon tetrachloride)
- Type: Covalent
- Reason: Both Carbon (C) and Chlorine (Cl) are non-metals.

Formulas for naming compounds:
The formulas for compounds are given in the question (KCl, NCl₃, ICl, MgCl₂, PCl₅, SiCl₄, PCl₃, CaCl₂, CsCl, CuCl₂, CrCl₃, CCl₄). Therefore, this section seems to be asking you to write the chemical symbols for the mentioned compounds correctly, which we have done above already.

I hope this helps! Let me know if you need further assistance.
