Different spheres make up different elements

Question 1

Order of models

Answer 1

Dalton’s
Thomson’s
Rutherford’s
Bohr’s

Question 2

Thomson’s model

Answer 2

Plum pudding model
Positively charged cloud with small negatively charged particles inside (electrons)

Question 3

Rutherford’s model

Answer 3

Fired alpha particles at gold sheet
Most alpha particles (+ charged) passed through gold atoms
Has positive nucleus and electrons around

Question 4

Bohr’s model

Answer 4

E- exist in fixed orbits not between them
Each shell has fixed energy
when e- moves between shells electromagnetic radiation is emitted or absorbed, because energy of shells are fixed, radiation has fixed frequency
