Question

Which of the following Lewis structures is the most correct structure for H2O?

Picture attached

Answer 1

Is D the correct answer?

Answer 2

Please help anybody :(

Answer 3

What are the rules for making Lewis structures? What makes D the best option?

Answer 4

Hydrogen has 1 valence electron and oxygen has 6 valence electrons so the lewis structure must account for a total of 1*2+6=8 electrons meaning there must be a total of 8 electrons in the structure

Answer 5

option C also has 8 electrons, what makes D better than C?

Answer 6

H can only have 2 electrons so when you write H-O-H each bond represents 2 electrons so now you've accounted for 4 of the 8 electrons, the other 4 must be lone pairs(dots) on the oxygen atom because they can't go on the hydrogen atom since hydrogen will only accept 2 electrons and each hydrogen already has 2 electrons

Answer 8

that's a good argument, entirely correct. GJ
