Atomic Structure Model Scientists Flashcard

Front

What equation did Erwin Schrodinger develop that treats electrons in atoms as waves?

Back

The Schrödinger equation.

Front

What conclusion did Ernest Rutherford reach from his Gold Foil Experiment?

Back

The atom is mostly empty space with a tiny, positively charged, dense center called the nucleus.

Front

Who discovered the existence of neutrons?

Back

James Chadwick.

Front

What is the uncertainty principle developed by Werner Heisenberg?

Back

It states that it is impossible to determine simultaneously both the position and the velocity of an electron.

Front

What atomic theory did John Dalton propose in 1803?

Back

The atomic theory of matter, which states that matter is composed of atoms.

What is the main contribution of Erwin Schrodinger to atomic theory?

Back

He developed a wave equation that describes the behavior of electrons in atoms.

What role do neutrons play in the atomic structure?

Back

Neutrons contribute to the mass of the atom and help stabilize the nucleus.

Front

How does the uncertainty principle affect our understanding of electron behavior?

Back

It implies that we cannot know both the exact position and momentum of an electron at the same time.

Front

What was the significance of John Dalton's atomic theory?

Back

It laid the foundation for modern chemistry by proposing that matter is made of indivisible atoms.
