Answer 4

First one

Look up S (sulfur’s) atomic number. That’s how many protons sulfur has. Now, since the charge is negative, it’s an anion. Finally, since the charge is -2, that means it has 2 more electrons than protons (take the # of protons and add 2)

Answer 5

Second one

I’m not exactly sure, because they only give you the number of electrons. You could try assuming this is a neutral atom with 5 protons as well. Look up the element on the p table that corresponds to 5 protons and write the symbol in the first blank.

(Again not 100% sure on this one)
