Model B: In this model the atom is a solid sphere that cannot be divided up into smaller particles or pieces. The atom is neutral and has no charge. Atoms of the same element are

mad of the same types of atoms.

Model D: In this model the atom is a sphere containing negatively charges particles

embedded in it. These small negative particles were originally called “corpuscles”

and later called electrons. However it was recognized that the atom is neutral (no

charge) so there must be an equal positive charge in the atom to offset the negative

charge of the electrons. Since no other particles were known at this time the rest of

the atom consisted of a positive charge.

It is possible to remove a negatively charged particle from an atom using electrical forces

(Thompson, 1897). Compare models B and D. Which model supports this evidence?

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
