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:
N: N is in Group 5A so it’s expected to gain 3 electrons to gain a –3 charge and become N3–.
N → –3
If the following elements were to form ions, what is the expectant charge? Drag the appropriate elements to their respective bins.
