What did Thomson's atomic theory model look like?
A ring with gold foil in the middle.
Electrons orbiting the nucleus like the planets around the sun.
A cloud of electrons floating around the nucleus.
A scoop of chocolate chip ice cream. It had electrons scattered within a ball of positive charge.
What did Bohr's atomic theory model look like?
A ring with gold foil in the middle.
Electrons orbiting the nucleus like the planets around the sun.
A cloud of electrons floating around the nucleus.
A scoop of chocolate chip ice cream. It had electrons scattered within a ball of positive charge.
The cloud model is what we use for the atomic theory now. What does the cloud model look like?
A ring with gold foil in the middle.
Electrons orbiting the nucleus like the planets around the sun.
A cloud of electrons floating around the nucleus.
A scoop of chocolate chip ice cream. It had electrons scattered within a ball of positive charge.
What did Rutherford discover about atoms?
An atom is always negatively charged.
An atom is mostly empty space, but has a dense positively charged center(nucleus).
An atom is always positively charged.
All particles will pass straight through gold foil with no change in path.
