Answer

Chlorine is located in Group 7A, meaning that it only needs to gain one electron in order to obtain a noble gas electron configuration. Therefore, it is expected to form negative ions. Calcium is located in Group 2A, meaning that it only needs to lose two electrons in order to obtain a noble gas electron configuration. Therefore, it is expected to form positive ions. Phosphorus is located in Group 5A, meaning that it only needs to gain three electrons in order to obtain a noble gas electron configuration. Therefore, it is expected to form negative ions. Selenium is located in Group 6A, meaning that it only needs to gain two electrons in order to obtain a noble gas electron configuration. Therefore, it is expected to form negative ions. Copper is a transition metal with multiple oxidation states. Therefore, it is expected to form positive ions. Tin is a metal with multiple oxidation states. Therefore, it is expected to form positive ions. Potassium is located in Group 1A, meaning that it only needs to lose one electron in order to obtain a noble gas electron configuration. Therefore, it is expected to form positive ions. Copper is a transition metal with multiple oxidation states. Therefore, it is expected to form positive ions.
