`CO` is stable , but analogous `SiO` is not stable . Why ?

Explanation

To understand why carbon monoxide (CO) is stable while silicon monoxide (SiO) is not, we can analyze the properties of carbon and silicon, which are in the same group of the periodic table.

### Step-by-Step Solution:

1. **Group Similarity**: Both carbon (C) and silicon (Si) belong to Group 14 of the periodic table. This means they share similar chemical properties, but there are significant differences due to their positions in the periodic table.

2. **Atomic Size**: Carbon has a smaller atomic size compared to silicon. As we move down the group from carbon to silicon, the atomic size increases. This larger size in silicon affects its bonding capabilities.
