In metals, the properties of malleability and ductility are explained by the fact that metallic atoms

a. roll past metallic bonds and form new bonds.

b. roll over without breaking their bonds.

c. conduct electricity by constantly moving electrons.

d. bounce light off of their sea of electrons.

B. roll over without breaking their bonds.

Explanation:

When metal plates are formed in different shapes and used to mold in different shapes than it can be done easily due to its ductility and malleability.

So here the bonds between the molecules or between the atoms is strong enough such that when we mold them of try to change the shape then these bonds will not break and they converts into shapes that is required.

So here we can say that correct answer for this property which requires malleability and ductility is given as

B).  It can be rolled over without breaking the bonds.

it's a b and
