Question

Carbon atoms are able to

 give off electrons to form negative carbon ions

 bond with other carbon atoms to form long chains

 gain four extra electrons to form positive carbon ions

 form five single covalent bonds with their valence electrons

Can you eliminate any of these?  i can. :) Carbon only has four valence electrons, so choice D is impossible. Do you see any other impossible answers?

anonymous · Answer

I would eliminate A  give off electrons to form negative carbon ions

anonymous · Answer

good :) And that means you can eliminate another one like it... which one is it?

anonymous · Answer

gain four extra electrons to form positive carbon ions

anonymous · Answer

which leaves me off with B

anonymous · Answer

Exactly. Carbon loves to make chains with itself! :D If you ever need to know, it is called 'catenation' when carbon atoms do this.
