Solution: From what you know about ion formation and the periodic table, which ion would be unlikely to occur?a. Rb +b. Ca 2+c. Al 3+d. Na 2+e. All of these ions are common ions.

Solution: From what you know about ion formation and the periodic table, which ion would be unlikely to occur?a. Rb +b. Ca 2+c. Al 3+d. Na 2+e. All of these ions are common ions.

Problem

From what you know about ion formation and the periodic table, which ion would be unlikely to occur?

a. Rb +

b. Ca 2+

c. Al 3+

d. Na 2+

e. All of these ions are common ions.

Solution

We’re being asked to determine which ion is unlikely to occur. Recall that when becoming an ion, the element tries to achieve the configuration of the nearest noble gas (shaded purple). For each group in the periodic table, we have:
