Se (atomic number 34) is in group 16 (or VIA depending upon the system your prof is using). Therefore, it needs two electrons to make 18 which is the next higher noble gas element of Kr(atomic number 36). Adding two electrons will make it a -2 charge.
Loss of 2 electrons
so what is the answer to the question
Selenium has the symbol Se2-, this means that selenium has
