2A.15

Postby Shanzey » Sun Oct 27, 2019 7:27 pm

Write the most likely charge for the ions formed by each of the following elements: (a) S; (b) Te; (c) Rb; (d) GA; (e) Cd.

In order to do this problem, do you have to find the electron configuration to tell what the charge of the ion is, or are charges a period table trend that we must have memorized?

In approaching a problem like this, it is best to determine the number of valence electrons to figure out the most likely charge for the ions instead of the entire electron configuration. For example, S has six valence electrons, and will most likely gain two electrons to fill the octet. Therefore, the most likely charge for an S ion would be - 2.

I think it is based off the valence electrons and how many are needed or exceeding the number allowed on each shell

To do this type of problem, you only need to know what makes an atom stable(full s and p orbital or lower energy) and know which atoms are metal(lose electrons) or nonmetal(gain electrons).
