Question

jerome is learning how the model of the atom has changed over time as new evidence was gathered. he has images of four models of the atom, but they are not in the correct order. in what order should jerome put these models to show the development from the earliest model of the atom to the most recent one?

Explanation:

To determine the order of atomic models from earliest to most recent, we analyze each model:

1. Model Y: Represents J.J. Thomson’s "plum pudding" model (late 1800s), where electrons are embedded in a positive "soup"—one of the earliest atomic models.
2. Model X: Represents Rutherford’s nuclear model (early 1900s), with a dense nucleus and electrons orbiting randomly (the "planetary" or "nuclear" model).
3. Model Z: Represents Bohr’s model (1913), where electrons orbit the nucleus in fixed energy levels (shells).
4. Model W: Represents the modern electron cloud model (mid-1900s to present), where electrons exist in probabilistic clouds around the nucleus (incorporating quantum mechanics).

Answer:

Y, X, Z, W
