If you can even see this, . if not i can repeat what it says.

Sulfur is a yellowish solid element (this is important to know)

to determine the element most like sulfur on the periodic table, you look at the elements next to sulfur, which would be Oxygen, Phosphorus, Chlorine, and Selenium

now, elemental oxygen and chlorine both come in the form of gases, which is denoted by the "white" letter  (Hg - mercury comes in the form of a liquid fyi)

so Oxygen and Chlorine are not the correct answer since a gas is different from a solid

Calcium is nowhere near Sulfur, so through process of elimination, the best answer would be Phosphorus
 

The answer is b metal denting

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
