Which statement describes a space-filling model of a molecule? A. The radii of the atoms are represented by the symbol of the atom surrounded by dots in the
space-filling model.

B. The radii of the spheres in a space-filling model are proportional in size to the radil of the atoms
they represent

C. The radii of the atoms present in the compound determine the length of the bonds in a space-
filling model.

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
