atoms want to have full outer energy shells to be \happy\. since an oxygen (o)
atom only has 6 valence electrons, it wants to find two more to be full.
drag and rotate the puzzle pieces to give the oxygen atom a full outer shell
using the hydrogen (h) atoms.

Explanation:

Step1: Determine the number of electrons oxygen needs

Oxygen has 6 valence electrons. A full outer shell (for the second shell) has 8 electrons. So, the number of electrons needed is \(8 - 6=2\).

Step2: Identify the compound formed

Oxygen (\(O\)) can bond with hydrogen (\(H\)). Each hydrogen atom has 1 valence electron. When oxygen bonds with two hydrogen atoms, it forms \(H_{2}O\) (water).

Answer:

1. 2 electrons.
2. \(H_{2}O\) (water).
