2- Atomic Structure

Question 1

How did Robert Boyle affect atomic structure?

Answer 1

He stated matter was made of tiny particles that he called corpuscles.

Question 2

How did John Dalton affect atomic structure?

Answer 2

Thought that all matter was made of tiny particles, which he imagined as tiny solid balls

Question 3

How did Henri Becquerel affect atomic structure?

Answer 3

He discovered radioactivity, concluding that there was something inside the atom

Question 4

How did J.J Thompson affect atomic structure?

Answer 4

Theorised the atom was a circular mass of positive charge with negatively charged clumps randomly scattered on top. (Plum pudding model)

Question 5

How did Ernest Rutherford affect atomic structure?

Answer 5

In 1905, he did an experiment directing beams of alpha particles at a thin gold sheet, and because some reflected and others went straight through, he concluded the atom is mostly empty space.

Question 6

How did Niels Bohr affect atomic structure?

Answer 6

Theorised electrons moved around the nucleus at fixed energy levels(shells)

Question 7

How did Erwin Schrödinger affect atomic structure?

Answer 7

Said that electrons don’t follow strict orbits and instead are found in orbitals, moving randomly around the nucleus

Question 8

How did James Chadwick affect atomic structure?

Answer 8

He found evidence of particles within the atom with mass but no charge(neutrons)
