Which describes ernest rutherford’s experiment? positive particles are fired at gold foil. most bounce back, but some pass through. negative particles are fired at gold foil. most bounce back, but some pass through. positive particles are fired at gold foil. most pass through, but some bounce back. negative particles are fired at gold foil. most pass through, but some bounce back.

The answer it's actually right, " Positive particles are fired at gold foil. Most pass through, but some bounce back. "

The statement "Positive particles are fired at a gold foil. Most pass through but some bounce back" best describes Ernest Rutherford's experiment.

This is the correct answer because Rutherford used Alpha particles, which is the helium nucleus without the electrons. The alpha particles have a net positive charge of two.

In the experiment, most of the alpha particles passed through the gold foil because they did not come in close proximity with the dense positive nucleus. A lot of particles did not come in-contact with this nucleus because the atom has a very small nucleus. The few that deflected or bounced back had come in close proximity to the dense positive center of the atom.

ill try to . no promises tho.

explanation:

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
