Developing New Materials for Computer Chips

As part of a new research project, Jennifer and Robert were assigned to investigate the properties of indium (In) and tellurium (Te). Both these elements are used to make computer chips. As a result of their research, Jennifer and Robert hope to develop new computer chips that will be faster and less expensive to manufacture.

a. What is the atomic number of Te?

b. How many electrons are in an atom of Te?

c. Use the sublevel blocks on the periodic table to write the electron configuration and abbreviated electron

configuration for an atom of Te.

d. Write the group number and draw the Lewis symbol for Te.

e. Which is smaller, an atom of selenium or an atom of tellurium?

f. Which has a lower ionization energy, an atom of selenium or an atom of tellurium?
