Sulfur forms covalent bonds with chlorine and carbon, but forms ionic bonds with calcium and lithium. What is the BEST description for this difference in how oxygen behaves?
A. Sulfur bonds randomly with elements in unpredictable ways
B. Sulfur bonds with elements that have a smaller atomic mass
C. Electronegativity differences between bonding elements allow electrons to be either shared or donated
D. The difference in atomic radii between the groups accounts for the difference in behavior

step-by-step explanation:

i need mutiple choices

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
