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 In?
b. How many electrons are in an atom of In?
c. Use the sublevel blocks on the periodic table to write the electron configuration and abbreviated electron configuration for an atom of In.
d. Write the group number and draw the Lewis symbol for In.
e. Which is larger, an atom of indium or an atom of iodine?
f. Which has a higher ionization energy, an atom of indium or an atom of iodine?
