Question

Please help!!! Rudri studies for her physical science test on the history of the atomic model. She creates a table to show how the atomic model has changed over time. Which represents the correct order of development for the atomic model?

A. w/x/y/z
B.y/x/z/w
C.x/y/w/z
D.x/z/w/y

Answer 1

c on edge

Step-by-step explanation:

Answer 2

The correct answer: C.x/y/w/z

x-Atomic model which describes atom as solid indivisible sphere is Dalton’s model of atom (1803),

y- Atomic model which says that electrons are embedded in a cloud of positive charge is Thomson’s model of atom (“plum pudding”, 1904),

w- Atomic model which says that electrons orbit the center in specific region called energy levels is Bohr’s model of atom (planetary model, 1913). According to this model electrons move around the nucleus.

z- Atomic model which says that electrons move around the center in negatively charged cloud is Schrodinger’s model of atom (quantum model, 1926).
