Draw the structures of (i) `BeCl_(2)` (vapour) (ii) `BeCl_(2)` (solid).

Explanation

To draw the structures of BeCl₂ in both vapor and solid states, we will follow these steps:

### Step 1: Understand the molecular geometry in vapor state
In the vapor state, BeCl₂ exists as a monomer. The central beryllium (Be) atom is bonded to two chlorine (Cl) atoms. Since beryllium has only two valence electrons, it forms two covalent bonds with chlorine atoms. The molecular geometry is linear due to the arrangement of the electron pairs around the beryllium atom.

**Hint:** Remember that the geometry can be predicted using VSEPR theory, which states that electron pairs will arrange themselves to minimize repulsion.

### Step 2: Draw the structure of BeCl₂ in vapor state
