1. Determine the number of valence electrons for each atom:
* Oxygen (O): Group 16, so it has 6 valence electrons.
* Fluorine (F): Group 17, so it has 7 valence electrons.
2. Calculate the total valence electrons:
* Oxygen: 6 electrons
* Fluorine (x2): 7 electrons x 2 = 14 electrons
* Total: 6 + 14 = 20 electrons
Therefore, you need a total of 20 electrons to form the OF2 molecule.
Important Note: This calculation focuses on valence electrons, which are the ones involved in bonding. The total number of electrons in the molecule will be higher, including the core electrons.
