6.  T or F:  Images of atoms produced by scanning tunneling electron microscopes are pictures of actual atoms and prove beyond a doubt that atoms exist.

 

False:  Images of atoms produced by scanning tunneling electron microscopes are not pictures, but are the result of computer generated calculations.

 

The types of signals made by an SEM can include secondary electrons, back scattered electrons, characteristic x-rays and light (cathodoluminescence). These signals come from the beam of electrons striking the surface of the specimen and interacting with the sample at or near its surface. In its primary detection mode, secondary electron imaging, the SEM can produce very high-resolution images of a sample surface, revealing details about 1 to 5 nm in size. Due to the way these images are created, SEM micrographs have a very large depth of focus yielding a characteristic three-dimensional appearance useful for understanding the surface structure of a sample. This great depth of field and the wide range of magnifications (commonly from about 25 times to 250,000 times) are available in the most common imaging mode for specimens in the SEM, secondary electron imaging, such as the micrographs displayed on the web page below.

 

Characteristic x-rays are the second most common imaging mode for an SEM. X-rays are emitted when the electron beam removes an inner shell electron from the sample, causing a higher energy electron to fill the shell and give off energy. These characteristic x-rays are used to identify the elemental composition of the sample. Back-scattered electrons (BSE) that come from the sample may also be used to form an image. BSE images are often used in analytical SEM along with the spectra made from the characteristic x-rays as clues to the elemental composition of the sample.

7.  Calculated electron microscope images are part of the large amount of _________ evidence that indicates atoms exist.

 

Such calculations images are part of the large amount of indirect evidence that indicates atoms exist. 

 

8.  When two or more atoms link together, they form a what, which has its own unique properties?

9.  T or F:  A water molecule is formed when an oxygen atom links together with two sodium atoms.

 

False:  A water molecule is formed when an oxygen atom links together with two hydrogen atoms.

10.  Y or N:  A molecule is broken down into its constituent atoms.  Do these atoms have the same properties as the molecule?

 

No:  When a molecule is broken down into its constituent atoms, the atoms produced do not have the same properties as the molecule.

 

11.  When salt is dissolved in water, it actually breaks down into two different substances.  Is salt composed of atoms or molecules?

 

When salt is dissolved in water, it actually breaks down into two different atomic substances, sodium and chloride.
