What did Rutherford call the region that deflected the alpha particles?
Nucleus.
How did Rutherford know the nucleus was positively charged?
the nucleus is positively charged because it bounces right off of the gold foil
What are helium atom nucleus?
The nucleus of a helium atom is composed of two protons and two neutrons. Alpha particles have the same composition as the nucleus of a helium atom.
How does radioactivity create new elements?
One way that elements decay is by alpha-emission. That means that the nucleus of the atom spews out alpha particles. An alpha particle is made of two protons and two neutrons, like a helium nucleus. Of course, once an alpha particle is emitted, the number of protons in the nucleus decreases, and the element changes with the number of protons.
Which observations helped Rutherford determine that atoms have tiny dense positively charged nuclei?
A+ answer: A few of the alpha particles in his expeirment were deflected from the gold foil at large angles. Scattering pattern of alpha particles 'shot' at a thin gold foil. Most went straight thru showing the nucleus was very small. Analysis of the scattering showed electrical repulsion, not that the particles actually hit the nucleus and bounced off.
What happens to a radioactive nucleus when it emits alpha particle and What happens to a radioactive nucleus when it emits alpha particle?
dude..
Which particles is similar to a He nucleus?
The so-called alpha particles ARE helium nuclei.
Type of nuclear decay consisting of a helium nucleus?
Alpha decay. Alpha particles are the same as a helium-4 nucleus.
What do you think are the chances of alpha particle directly hitting the nucleus?
What do you think are the change of the alpha particles directly hitting the nucleus
What did Rutherford call the region that deflected the alpha particles?
Nucleus.
Why the alpha particles could not smash the nucleus apart?
The alpha particle is positively charged (as is the nucleus) and is heavy compared with the neutron that is neutral and lighter than the alpha particle.Another viewpoint:It depends what experiment the question is about. For example, over a hundred years ago, Rutherford bombarded gold foil with alpha particles and some "bounced off" what we now call the nucleus of the atoms. However, about ten years later he did experiments in which alpha particles did indeed "split" atomic nuclei. So, sometimes alpha particles can certainly smash a nucleus apart.
What type of particles are released as part of alpha decay?
It is the alpha particle, which is actually a helium-4 nucleus, that is emitted during alpha decay. The helium-4 nucleus, you'll recall, consists of two protons and two neutrons.See the links below for more information.
Why did the path of only some alpha particles deviate?
nucleus of the atom has positive charge.alpha particles are also positively charged.like charges repel each other.so alpha particles passing near the nucleus are repelled and deviated from the normal path
Alpha particles ejected from the nucleus travel at the speed of light?
No. Alpha particles are helium nuclei; such nuclei have a mass, and can therefore NOT travel at the speed of light.
Why was existence of a tiny massive and positively charged nucleus was deduced from the observations?
Why or how? The number of alpha particles deflected was small ... indicating the nucleus was small. The deflection of an even smaller amount of alpha particles almost straight back toward the emitting source proved that the nucleus was heavier than the alpha particle. According to previous atomic theory, the alpha particles should have all gone straight through the metal foil, with none deflected. Math calculations based on the deflection pattern showed that the nucleus was repelling the alpha particles, that they were not actually hitting and bouncing off the nucleus... this showed that the nucleus was positively charged.
Do alpha particles contain helium?
No, they're just similar to a helium nucleus.
How did Rutherford know the nucleus was positively charged?
the nucleus is positively charged because it bounces right off of the gold foil
