What did Rutherford add to the atomic model?
He discovered that an atom has a very dense and very tiny positively charged nucleus. He named the positively charged particles protons.
Who explained the behavior of positively charged particles being deflected from a metal foils as the nucleus?
ernest Rutherford
What part of the atom was discovered by Rutherford?
Rutherford discovered the atomic nucleus and the proton. A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
What did Rutherford gold foil experiment suggest about the structure of an atom?
1) Atoms were mostly empty space (because most alpha particles went straight through the gold foil) 2) Atoms had a dense nucleus (because few alpha particles bounced straight back from the atoms) 3) The nucleus of atoms were positively charged (some alpha particles were deflected at large angles)
Who is Rutherford in regards to atoms?
Rutherford discovered the atomic nucleus and the proton. A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
The term Rutherford gave to the positively charged particles in the nucleus of an atom?
In 1920, Rutherford gave the name proton to the positively charged particles in the nucleus of an atom.
Why does rutherford's gold-foil experiment conclude that the atom is mostly empty space with a small massive positively charged center?
because few particles bounced back
What was the term Rutherford gave positively charged particles?
protons
How did Rutherford know the nucleus was positively charged?
the nucleus is positively charged because it bounces right off of the gold foil
What scientist discovered positively charged subatomic particles?
Ernest Rutherford in 1919.
What was the term Rutherford gave the positively charged particles in the nucleus of an atom?
Proton
What was the term Rutherford gave to the positively charged particles in the nucleus of an atom was?
Proton
What did Rutherford say about the small number of particles that bounced straight back?
Rutherford fired alpha particles at a sheet of atoms in order to determine the atomic structure. The alpha particle is positively charged. Those particles that bounce straight back are the ones that hit the nucleus of the atom and were repelled by the nucleus's positive charge.

What are the main ideas of e Rutherford gold foil experiment?
basically, Rutherford shot postively charged particles at a thin sheet of gold foil. most of the particles passed straight through, but some bounced off at sharp angles. This implies that most of the atom is empy space (which is why most of the particles go straight throught) , but there is a positively charged nucleus at the center (which repels the postively charged particles, so if a particle hits the nucleus, it bounces off )
What was Rutherford's threoy of the atom?
Rutherford's Theory was that atom is mostly empty space, thus explaining the lack of deflection of most of the alpha particles, when he tested out the Gold-Foil Experiment. Rutherford predicted that all the alpha particles would go through the gold foil, however, when tested, some of the alpha particles reflected back, bounced off the gold foil at very large angles.A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
