anonymous · Answer

2. has a tendency to attain nearest noble gas configuration by loosing its valence electrons to have an octet
3.has a tendency to attain nearest noble gas configuration by gaining electrons to complete a octet

1. It means the element S (look it up in the periodic table) has a net charge of -2
4. Again, look at the periodic table for how many electrons S atom has and then add/subtract the electrons that caused the net charge. Then rewrite the configuration. 

Hint: 1 electron carries -1 charge, 1 proton carries +1 charge
