Development of the atomic model

Chemistry

Which atomic model is the most commonly accepted model today?

Whose atomic model determined that an atom's positive charge is concentrated in the centre?

Alpha particles were repelled by a concentration of positive charge in the centre of the atom. 

Most of the atom is empty space meaning it was difficult for particles to maintain a straight path.

The mass of the atom is concentrated in the nucleus, which has a tiny volume.

They were attracted to electrons surrounding the nucleus, taking them off course.

During the alpha particle scattering experiment, why were some particles deflected at angles as they travelled through?

Electrons are at fixed distances from the nucleus.

Electrons exist in clouds orbiting in the nucleus.

Neutrally charged particles are located in the nucleus.

The positive charge is spread evenly throughout the atom.

Which **two** statements are correct about the Bohr's atomic model?

Match the scientist to the component of the atom they found evidence for.

An atom consists of protons, neutrons and {{}}.

Which subatomic particles are found in the nucleus?

Match the subatomic particle to its charge.

Which subatomic particle has an insignificant mass?

Which subatomic particle is in shells that orbit the nucleus?
