Can somebody help me please???
Ozone, O3 has a O-O-O connectivity.
1. Draw a lewis structure for ozone
2. Calculate the formal charge for each oxygen of ozone
3. Describe the shape of ozone

Mrs.Sue that is inappropriate!!!!! f it is the answer than say the answer is "blank"!!!!!!!!
Sure, I can help you with that.
1. To draw the Lewis structure for ozone (O3), we need to follow the octet rule, which states that atoms tend to gain, lose, or share electrons in order to have a full outer electron shell.
First, let's determine the total number of valence electrons for ozone. Oxygen is in Group 16 of the periodic table, so it has 6 valence electrons. Since we have three oxygen atoms in ozone, the total number of valence electrons is 6 x 3 = 18.
Next, we need to identify the central atom. In this case, the central atom is one of the oxygen atoms. The other two oxygen atoms will be bonded to it.
To draw the Lewis structure:
- Start by connecting the central oxygen atom to the other two oxygen atoms using single bonds. This will account for 6 electrons (2 from each oxygen-oxygen bond).
- Next, place the remaining 12 electrons around the oxygen atoms. Each oxygen atom will have 4 electrons around it, fulfilling the octet rule.
The final structure will have a double bond between the central oxygen atom and one of the other oxygen atoms, and single bonds between the central oxygen atom and the remaining oxygen atom. It will look like this:

O==O
2. Now, let's calculate the formal charge for each oxygen atom in ozone. The formal charge is the difference between the number of valence electrons an atom has in an isolated (neutral) state and the number of electrons assigned to it in a Lewis structure.
To calculate the formal charge:
- Determine the number of valence electrons an atom has in an isolated state. Oxygen has 6 valence electrons.
- Count the number of lone pair electrons (dots) around the atom in the Lewis structure and subtract it from the number of valence electrons.
- Count the number of bonds the atom has in the Lewis structure and subtract it from the number of valence electrons.
- The result is the formal charge.
In the Lewis structure of ozone:
- The central oxygen atom has 4 lone pair electrons and 2 bonds. So, the formal charge is 6 - 4 - 2 = 0.
- The other two oxygen atoms have 3 lone pair electrons and 1 bond each. So, the formal charge for each of them is 6 - 3 - 1 = +2.
3. Finally, let's describe the shape of ozone. The shape of a molecule is determined by its electron domain geometry and molecular geometry. In the case of ozone:
- Electron domain geometry: The central atom has 3 electron domains (2 bonds and 1 lone pair). According to VSEPR theory, this results in a trigonal planar electron domain geometry.
- Molecular geometry: However, due to the presence of a lone pair on the central atom, the molecular geometry is slightly bent, resulting in a bent or V-shaped molecule.
I hope this helps! Let me know if you have any other questions.
