Consider a Si atom with a charge of -2 and a mass number of 28. This type of ion is called alan How many protons in the nucleus? How many neutrons in the nucleus? How many electrons in the electron cloud? If this Si lost 2 electrons, what would the charge be?

I'm sorry i cant you if you don't list the elements : (

The answer is c.  h+  and oh−  react to form water (h2o). i just took the test and i got it right. hope this !
