Give the number of electrons in the species `H_2^+. H_2, and O_(2)^+`.

Explanation

To determine the number of electrons in the species \( H_2^+ \), \( H_2 \), and \( O_2^+ \), we can follow these steps:

### Step 1: Determine the number of electrons in \( H_2 \)
- The molecule \( H_2 \) consists of two hydrogen atoms.
- Each hydrogen atom has an atomic number of 1, which means it has 1 electron.
- Therefore, for \( H_2 \):
\[
\text{Number of electrons in } H_2 = 2 \times 1 = 2 \text{ electrons}
