How does Rutherford atomic model differ from Thomson's?

Answer 1

Before his experiment, it was assumed that all of the constituents of an atom were distributed in a uniform structure. Rutherford used a very thin foil made of gold, only a few atoms thick, which he bombarded with alpha particles. Most of the alpha particles were expected to punch through with only a small amount of energy loss, but some bounced back, a phenomenon likened to "shooting a cannon ball at a piece of tissue and having the cannon ball bounce back."

The nucleus of the atom contains the majority of the mass and has a diameter that is much smaller than the atom; for most atoms, the nucleus is about 100,000 times smaller than the size of the atom; the remainder of the atom is empty space with a cloud of electrons buzzing around. This revealed that some part (or parts) of the atom must be extremely dense.

Answer 2

Rutherford's model suggested that atoms have a small, dense nucleus at their center, where most of the mass is concentrated, and electrons orbit the nucleus. In contrast, Thomson's model proposed a uniformly distributed positive charge throughout the atom, with electrons embedded like raisins in a pudding. Rutherford's model replaced the uniform distribution of positive charge with a concentrated nucleus, leading to a more accurate representation of atomic structure.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
