What is the shape of chromate ion ?

Explanation

To determine the shape of the chromate ion (CrO4^2-), we can follow these steps:

### Step 1: Identify the formula and oxidation state
The chromate ion is represented as CrO4^2-. Here, chromium (Cr) is in the +6 oxidation state.

### Step 2: Count the total number of valence electrons
- Chromium has 6 valence electrons.
- Each oxygen atom contributes 6 valence electrons, and there are 4 oxygen atoms: 4 × 6 = 24 electrons.
