e. The red box
Work Step by Step
To answer the questions in this problem, we want to take a look at the front cover of our book at the periodic table there.
a. The blue box corresponds to the element potassium, atomic number 17, and the green box corresponds to the element silver, atomic number 47. Potassium is located in group 1A or 1 on the periodic table called the alkali metals. The alkali metals lie on the metal side of the periodic table and form 1+ cations, which corresponds to their group number.
Silver is a transition metal located in group 11 or 1b of the periodic table. It also forms 1+ cations.
b. The gray box corresponds to the element magnesium, atomic number 12. It is located in group 2A or 2 on the periodic table called the alkaline earth metals. These elements lie on the metal side of the periodic table and form 2+ cations, which corresponds to its group number.
c. The yellow box corresponds to the element selenium, atomic number 21. It is located in group 3B or 3 on the periodic table. This element lies on the metal side of the periodic table and forms 3+ cations, which corresponds to its group number.
d. The violet box corresponds to the element iodine, atomic number 53. It is located in group 7A or 17 on the periodic table. This element lies on the nonmetal side of the periodic table and forms 1- anions.
e. The red box corresponds to the element oxygen, atomic number 8. It is located in group 6A or 16 on the periodic table. This element lies on the nonmetal side of the periodic table and forms 2- anions.
