Is `CaF_(2)` linear or bent or neither of the two ? Justify .

Explanation

To determine whether \( \text{CaF}_2 \) is linear, bent, or neither, we can analyze the structure and bonding of the compound step by step.

### Step 1: Identify the type of bond in \( \text{CaF}_2 \)
- Calcium (Ca) has an atomic number of 20, and its electronic configuration is \( [\text{Ar}] 4s^2 \). This means it has 2 electrons in its outermost shell.
- Fluorine (F) has an atomic number of 9, and its electronic configuration is \( [\text{He}] 2s^2 2p^5 \). This means it has 7 electrons in its outermost shell.
- Calcium tends to lose its 2 valence electrons to achieve a stable octet, while fluorine tends to gain 1 electron to complete its octet.

### Step 2: Formation of \( \text{CaF}_2 \)
