Answer

To determine the total number of species having a square planar shape from the given list of compounds with the formula XZ₄, we will analyze each compound step by step.

### Step-by-Step Solution:

1. **Identify the Compounds**: The given compounds are:
- XeF₄
- SF₄
- SiF₄
- BF₄⁻
- BrF₄⁻
- [Cu(NH₃)₄]²⁺
- [FeCl₄]²⁻
- [CoCl₄]²⁻
- [PtCl₄]²⁻

2. **Analyze Each Compound**:
- **XeF₄**:
- Xenon (Xe) has 8 valence electrons.
- It forms 4 bonds with fluorine and has 2 lone pairs.
- The shape is square planar due to the arrangement of 4 bonding pairs and 2 lone pairs.

- **SF₄**:
- Sulfur (S) has 6 valence electrons.
- It forms 4 bonds with fluorine and has 1 lone pair.
- The shape is see-saw, not square planar.

- **SiF₄**:
- Silicon (Si) has 4 valence electrons.
- It forms 4 bonds with fluorine and has no lone pairs.
- The shape is tetrahedral, not square planar.

- **BF₄⁻**:
- Boron (B) has 3 valence electrons and gains 1 from the negative charge.
- It forms 4 bonds with fluorine and has no lone pairs.
- The shape is tetrahedral, not square planar.

- **BrF₄⁻**:
- Bromine (Br) has 7 valence electrons and gains 1 from the negative charge.
- It forms 4 bonds with fluorine and has 2 lone pairs.
- The shape is square planar due to the arrangement of 4 bonding pairs and 2 lone pairs.

- **[Cu(NH₃)₄]²⁺**:
- Copper (Cu) in +2 oxidation state has 9 d-electrons.
- It forms 4 bonds with ammonia (NH₃) and undergoes dsp² hybridization.
- The shape is square planar.

- **[FeCl₄]²⁻**:
- Iron (Fe) in +2 oxidation state has 8 d-electrons.
- It forms 4 bonds with chloride (Cl) and undergoes dsp² hybridization.
- The shape is square planar.

- **[CoCl₄]²⁻**:
- Cobalt (Co) in +2 oxidation state has 7 d-electrons.
- It forms 4 bonds with chloride (Cl) and undergoes sp³ hybridization.
- The shape is tetrahedral, not square planar.

- **[PtCl₄]²⁻**:
- Platinum (Pt) can undergo dsp² hybridization.
- It forms 4 bonds with chloride (Cl) and has a square planar shape.

3. **Count the Square Planar Species**:
- From the analysis, the species with square planar shape are:
- XeF₄
- BrF₄⁻
- [Cu(NH₃)₄]²⁺
- [FeCl₄]²⁻
- [PtCl₄]²⁻

Thus, the total number of species having a square planar shape is **5**.

### Final Answer:
The total number of species having a square planar shape is **5**.
