Ionic Lewis Structure

A model of a compound is shown. Which of the following identifies the compound and explains why? 

• Network covalent solid because there are covalent bonds between the atoms.

• Ionic solid because there are positive and negative charges attracted to each other.

• Molecular compounds because metals and nonmetals are sharing electrons.

• Metallic solid because electrons are distributed among the positive nuclei.

• gain

Which of these could be the lewis dot diagram for an oxygen anion?

• A

• B

• C

• D

Answer explanation

Oxygen has 6 valence electrons, but it wants 8. Therefore, it will steal 2 electrons so that it has a total of 8 electrons. Choice A has 8 electrons.
