'This piece of chalk has mass. So the atoms that make up this piece of chalk also have mass.' Which of the following is true regarding the above argument?

The chalk-and-atoms argument is a non-formal, informal fallacy, not a valid deduction.

It reasons that because the whole piece of chalk has mass, each atom composing it must have mass.

A property of the whole is transferred without warrant to its individual parts.

What holds of an aggregate need not hold of each component taken singly.

This unjustified shift from whole to part is a fallacy of division, an informal error.

Since the flaw lies in content rather than logical form, it counts as an informal fallacy.
