Draw the structure of chromium pentoxide and predict the oxidation number of chromium in it

Explanation

To solve the question of drawing the structure of chromium pentoxide (CrO5) and predicting the oxidation number of chromium, we will follow these steps:

### Step 1: Understanding the Composition of Chromium Pentoxide
Chromium pentoxide consists of one chromium (Cr) atom and five oxygen (O) atoms. The formula is CrO5.

### Step 2: Drawing the Structure of Chromium Pentoxide
1. **Identify the bonding**: In CrO5, chromium is bonded to five oxygen atoms. The structure features one chromium atom at the center.
2. **Oxygen Atoms**: Four of the oxygen atoms are bonded to chromium through single bonds, and one oxygen atom is bonded through a double bond.
