Lewis

Excuse me sir but can you see, the skies about to open up, Yes I seem a little lost, and my minds a little off, Ask me do I think about her, not enough to lose my place, Why must I always be the one,...

The beer was talking and it seemed a little bored Suggested walking for awhile Thought it'd be dramatic if we walked all night But I got tired, so I came home Lay back on the couch to watch TV The...

Hi, this is Dr. B. Let's do the Lewis structure for Beryllium Chloride. On the periodic table Beryllium is in group 2, it has 2 valence electrons; Chlorine--group 7--7, but we have 2 of those...

This is the HCO3 minus Lewis structure. For HCO3-, we have a total of 24 valence electrons. When we see an H in front of a polyatomic structure like the CO3- here, that means the H will be attached on...

Hi, this is Dr. B. Let's do the SO2 Lewis structure. On the periodic table: Sulfur, 6 valence electrons. Oxygen has 6. We have two Oxygens, though, for a total of 18 valence electrons....

This is the NO3- Lewis structure: the nitrate ion. Nitrogen has 5 valence electrons. Oxygen has 6, we have 3 Oxygens, and we need to add 1 for this valence electron up here. That gives us a total of 5...

For the N2 Lewis structure, we have five valence electrons for Nitrogen--it's in group 5 or 15 on the periodic table. We have two Nitrogens. Multiply those together, we have a total of 10...

OK, this is Dr. B. We're going to do the Lewis structure for NH3: ammonia or Nitrogen trihydride. On the periodic table, Nitrogen is in group 5 or 15 so it has 5 valence electrons, and then...

Hi, this is Dr. B. Let's do the Lewis structure for C2H6, ethane. On the periodic table, Carbon is in group 4 or 14, so it has 4 valence electrons, but we have 2 of them. So let's...

OK, we're going to do the Lewis dot structure for O2. Let's start. Looking on the periodic table, we can find Oxygen in group 6 or 16, and that means it has 6 valence electrons. But we...
