Development of atomic model synergy

Which is the Dalton model?

• Spheres

• Plum puddings

• electrons orbiting a single, positive charge

• electrons orbiting a nucleus of protons and neutrons.

Which model came first?

• Spheres

• Plum puddings

• electrons orbiting a single, positive charge

• electrons orbiting a nucleus of protons and neutrons.

Which model came AFTER the Dalton (spheres) model?

• Spheres

• Plum puddings

• electrons orbiting a single, positive charge

• electrons orbiting a nucleus of protons and neutrons.

Which model came AFTER the plum pudding model?

• Spheres

• Plum puddings

• electrons orbiting a single, positive charge

• electrons orbiting a nucleus of protons and neutrons.

Which model do scientists currently believe to be correct?

• Spheres

• Plum puddings

• electrons orbiting a single, positive charge

• electrons orbiting a nucleus of protons and neutrons.

Why did Dalton suggest that atoms were like spheres?

• Because he had discovered electrons

• Because he had discovered protons

• Because he had discovered neutrons

• To explain the properties of solids, liquids and gases

In the plum pudding model we have

• negative charges in a positive cloud.

• positive charges in a positive cloud.

• negative charges in a negative cloud.

• positive charges in a negative cloud.

In the plum pudding model we have

• negative charges in a positive cloud.

• positive charges in a positive cloud.

• negative charges in a negative cloud.

• positive charges in a negative cloud.

Why was the plum pudding model suggested?

• Because we have discovered electrons

• Because we have discovered protons

• Because we have discovered neutrons

• To explain the properties of solids, liquids and gases

Most recently. we have included neutrons in the atomic model. Why?

• Because we have discovered electrons

• Because we have discovered protons

• Because we have discovered neutrons
