Scientist- Atomic Theory

Discovered the neutron

For almost 100 years, the Law of Conservation of Mass was know as _________'s Law

Stated that all atoms of a given element are identical.

Discovered the electron

The image is an example of a(n)

The Heisenberg Uncertainty Principle states the more you know about momentum of an electron...

This states each orbital must be singly occupied across the sublevel before it is paired.

Gave us the "Plum Pudding Model" of the atom.

Electrons release photons as they move from the ______ state to the ______ state.

Stated if an apple were cut in half again & again you would arrive at something indivisible

Electrons in the outermost principle energy levels are referred to as

A precise amount of energy released or absorbed by an electron is called a

Performed the "Gold Foil Experiment"

Gave us the first atomic model of the atom.  The "Hard Sphere Model"

Performed the "Oil Drop Experiment"

Defined as 1/12th the mass of a Carbon-12 

A principle by which most atoms become more stable with eight electrons in the outer shell

The Pauli Exclusion Principle states that no 2 electrons in the same orbital may have the same

Metals ejecting electron with certain minimum frequencies of light are shown upon them is

Neils Bohr envisioned electrons in set energy levels.  What was his atomic model?

Stated all matter was made from earth, air, water, and fire.

Performed the "Cathode Ray Tube Experiment"

Discovered that atoms are mostly empty space.

What is the name of our modern model of the atom?

Stated that atoms of different elements are different because they have different masses.

Considered the "Father of Modern Chemistry"

Gave us the "Nuclear Model" of the atom.
