Sulfur also has 16 electrons which are placed into three electron shells. First one has 2 electrons, the second one has 8 electrons, and the third has 6.
 Atomic Number=16
 
sulfur has 32 - 16 = 16 neutrons.
   2 in the first electron shell,
 8 in the second, and the remaining 6 in the third.
To gain  a full 8 electrons in the third (outermost) electron shell, the sulfur atom can accept 2 electrons in an ionic bond
. Because hydrogen atoms can share one electron in a covalent bond
