Answer:
Tarnish,Striations,Shape,Color,Specific Gravity,Hardness,Ductility.
Explanation:
Ductility: Gold is usually very ductile in nature and will bend on pressure.Fool's Gold will break or resist the pressure.
Hardness: Gold(hardness scale 2.5) will most probably not scratch a copper surface (hardness of 3), but pyrite will very easily be able to do that. Even Gold will be scratched by copper pieces but copper can barely scratch other metals.
Color: Pyrite color is brass type. Gold has a little yellow to golden colour.
Tarnish :God can't be tarnished that easily whereas Pyrite can.

Answer:
Fluorine element has less orbitals than chlorine.
Explanation:
They are both in the same group so they have to gain the same amount of electrons(which will not effect shape)....However on going down the group one notices that the atoms get larger as more orbitals are needed to hold the electrons.
