Lewis Structure?

Question

I need some help finding out what the Lewis Structure is for hydrogen, cardon dioxide, and boron trihydride.

Thanks for your help.

Answer 1

I assume that you need Lewis Electron dot Structures for these. Hydrogen gas (H2) = H:H (atomic hydrogen = H. (Single dot))
For CO2 = O::C::O
For BH3 Put the hydrogens at 120 degree angles from each other and attached to boron with 2 e dots between them and the central boron.
