The mass number is equal to:
The number of Protons
The number of Neutrons
The number of Protons + the number of Electrons
The number of Protons + the number of Neutrons
Where do you find a proton?
In the nucleus
On the outside of the nucleus
Orbiting the nucleus
None of the above
The red subatomic particles are:
Proton
Neutron
Electron
Positron
The vacuum tube experiments, where a current was moved through a vacuum tube and deflected with a magnet proved that:
Atoms are mostly positive
Atoms have smaller charged particles like electrons
Atoms are mostly empty space
Protons determine the identity of the atom
The law of definite proportions supported the existence of atoms because:
Specific compounds can have different proportions of elements
Specific compounds always have the same proportion of each element
Mass is related to number of protons
Conservation of mass
What is an alpha particle most similar to?
A Helium nucleus
A Hydrogen nucleus
A proton
An electron
What did the Gold Foil Experiment prove?
That electrons exist and have mass
That Neutrons exist
That the nucleus exists and has positive charge
Conservation of Mass
The existence of isotopes is evidence of:
The existence of the proton
The existence of the neutron
The existence of the electron
The atom is mostly empty space
The evidence that atoms are mostly space was found through what?
The vacuum tube experiment
The experiments to find the Definite Proportions Law
The gold foil experiment
The experiments with gas filled balloons

True
False
