Answer the following question given this paragraph: Valence electrons also determine how wellif at allthe atoms of an element conduct electricity. The copper wires in the cable in the Figure below are coated with plastic. Copper is an excellent conductor of electricity, so it is used for wires that carry electric current. Plastic contains mainly carbon, which cannot conduct electricity, so it is used as insulation on the wires. Q: Valence electrons also determine how wellif at allthe atoms of an element conduct what? Choices: - water - pollution - light - electricity A:
electricity

Answer the following question given this paragraph: Neutralization reactions, like the other chemical reactions you have read about so far, involve electrons. Electrons are outside the nucleus of an atom. Certain other reactions involve the nucleus of an atom instead. These reactions are called nuclear reactions. You will read about them in the next chapter, "Nuclear Chemistry. ". Q: Where are electrons located in relation to the nucleus? Choices: - in the nucleus - In a sack attached to the nucleus - though the nucleus - outside the nucleus A:
outside the nucleus
