Answer the following question given this paragraph: Structures of the Nonmetals The structures of the nonmetals differ dramatically from those of metals. Metals crystallize in closely packed arrays that do not contain molecules or covalent bonds. Nonmetal structures contain covalent bonds, and many nonmetals consist of individual molecules. The electrons in nonmetals are localized in covalent bonds, whereas in a metal, there is delocalization of the electrons throughout the solid. The noble gases are all monatomic, whereas the other nonmetal gaseshydrogen, nitrogen, oxygen, fluorine, and chlorinenormally exist as the diatomic molecules H2, N2, O2, F2, and Cl2. The other halogens are also diatomic; Br2 is a liquid and I2 exists as a solid under normal conditions. The changes in state as one moves down the halogen family offer excellent examples of the increasing strength of intermolecular London forces with increasing molecular mass and increasing polarizability. Oxygen has two allotropes: O2, dioxygen, and O3, ozone. Phosphorus has three common allotropes, commonly referred to by their colors: white, red, and black. Sulfur has several allotropes. There are also many carbon allotropes. Most people know of diamond, graphite, and charcoal, but fewer people know of the recent discovery of fullerenes, carbon nanotubes, and graphene. Descriptions of the physical properties of three nonmetals that are characteristic of molecular solids follow. Q: Nonmetal structures contain what type of bonds? A:
OPTIONS:
- prevalent
- polymeric
- gravitational
- covalent

Answer: covalent

Question: Answer the following question given this paragraph: Light microscopes continued to improve and are still used today. However, to see extremely small objects, a different type of microscope, such as an electron microscope, must be used. Q: What type of microscope is used to see extremely small objects? A:
OPTIONS:
- optical microscope
- X-ray microscope
- ultrasonic microscope
- electron microscope
Answer: electron microscope

input with options: Answer the following question given this paragraph: Unlike oxygen, carbon dioxide is more concentrated in the blood in the capillaries surrounding the alveoli than it is in the air inside the alveoli. Therefore, carbon dioxide diffuses in the opposite direction. It moves out of the blood and into the air. Q: Which gas moves from the blood in the capillaries into the air? A:
OPTIONS:
- nitrogen
- carbon monoxide
- oxygen
- carbon dioxide
output: carbon dioxide

Q: Answer the following question given this paragraph: Sodium and chloride ions have equal but opposite charges. Opposites attract, so sodium and chloride ions attract each other. They cling together in a strong ionic bond. You can see this in row 2 of Figure above . Brackets separate the ions in the diagram to show that the ions in the compound do not share electrons. You can see animations of sodium chloride forming at these URLs:. Q: Why do sodium and chloride ions attract each other? A:

OPTIONS:
- sulfides attract
- magnetism
- like attracts like
- opposites attract

A: opposites attract

Answer the following question given this paragraph: The wind belts have names. The Trade Winds are nearest the Equator. The next belt is the westerlies. Finally are the polar easterlies. The names are the same in both hemispheres. Q: What is the name of the wind belt nearest the equator? A:
OPTIONS:
- tropical gusts
- cyclones
- doldrums
- trade winds
trade winds
