`BeF_(2)` and `H_(2)O` are both tri-atomic molecules but have different shapes. Discuss.

Text Solution

AI Generated Solution

To discuss the shapes of the triatomic molecules BeF₂ (beryllium fluoride) and H₂O (water), we need to analyze their molecular structures and the factors that influence their shapes. ### Step 1: Determine the Valence Electrons - **BeF₂**: Beryllium (Be) has 2 valence electrons, and each fluorine (F) has 7 valence electrons. Therefore, the total number of valence electrons in BeF₂ is: \[ 2 + 2 \times 7 = 16 \text{ valence electrons} \] ...
