Predict the common charges (hint: there are two) of the ions of tin. explain your reasoning in terms of electron configurations.

and

Explanation:-

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration  in terms of nearest noble gas for tin with atomic number of  50 and thus 50 electrons

It can lose two electrons from 5 p orbital to form or can lose 4 electrons from 5p and 5s to form .Tin loses electrons to acquire noble gas configurations to acquire stability.
