What is the parent geometry of hydrogen sulfide?

Which of the following shapes does not represent a 4 electron domain?

Select the most rational Lewis structure for SO₂ from the figure provided.

When drawing Lewis structures, straight lines are drawn in-between atoms to indicate bonds. Common bonding arrangements include single bonds, double bonds and triple bonds. From the options below, indicate how many electrons are represented by each

Please note: there is more than one correct answer (but you only need to select one!)

Which of the four resonance structures for the nitrate ion below is the least likely? Remember to consider the formal charge on each atom, and the number valence electrons in the structure.
