When looking at the periodic table there are 2 ways to name the groups. He is using the way that excludes the transition metals (d block). Making Boron group 3.
My thoughts exactly! Double bonds on both Oxygens (O=S=O) would bring the formal charge to zero for all atoms involved. Would this not be a better dot structure? I'm struggling to decide when formal charge trumps the octet rule and this video really set me back.
Look for coordinate covalent bonds or dative bonds in your textbook. Essentially, in these bonds, the electrons in bond pair is CONTRIBUTED BY ONE ATOM but SHARED BY BOTH ATOMS. Hence, this results in formal charges. Hope this helped.
great video, thank you Khan Academy
0:22 I believe Boron is in group 13, rather than group 3.
You are describing Br. That is barium instead of B which is boron
@@claudiawwjd8198 In the video he talks about Boron (B), not Barium (Ba). Also Bromine (Br) is in group 17.

Isn't there a better structure for SO2 with a double bond between each oxygen and the sulfur?

Believe that was an oversight in this video. Regardless, the logic stands that there are three electron clouds and angular structure.
why aren't the electrons on the two Oxygen also considered "lone pairs" and why arent they with their own electron cloud?
i dont understand why the oxygen is just giving two electrons arent there supposed to be bonds wont both sulfur and oxygen share electrons
