Answer

Charge: +2

Work Step by Step

Atoms of elements want to have the electron configuration of the nearest noble gas (in terms of number of electrons) on the periodic table. Strontium (Sr) is in group 2A, so it must lose two electrons to get the electron configuration of its nearest noble gas, Argon. Hence, the most common charge of a Strontium ion will be +2.
