Re: Lone pair electrons
For a lone pair it would be better just to put it as a dot rather than a line. The line usually means a single bond, so to be safe put it as a dot.

Re: Why can't hydrogen be a central atom? [ENDORSED]
Hydrogen is a special case. It can only form one bond so it won't help putting it in the center. Hydrogen atoms are recommended to be at the sides.

If you look at the topic "trick to balance" that may help you find an easier to way to balance the chemical equations. Hope it helps!

typically I set a certain amount of time each week just for chemistry, at least three times a week while also studying for a test the week before so I don't get overwhelmed
Thank you!
