more protons than electrons A+
What else can I help you with?
What are positively charged radioactive rays called?
alpha particles
What are alpha rays attracted to?
Magnetic fieldsNegatively charged objects
Are alpha particle negative or positive?
An alpha particle is a helium nucleus; it has a charge of +2.
When positively charged particles bounced back from the foil Rutherford called this?
Rutherford called this phenomenon the "scattering of alpha particles" which was a key observation that led to the development of the nuclear model of the atom.
Does alpha have a 1 plus charge?
An alpha particle has the charge 2+ and the mass 4.
What are positively charged radioactive rays called?
alpha particles
What happens to a positively-charged alpha particles that comes the positively-charged nucleus?
It will repel
When a beam of alpha particles passes between two electrically charged plates - which plate is the beam deflected toward?
The beam would be deflected to the negative plate, as alpha particles are Helium nuclei and are positively charged.
What are the charged particles in a nucleus?
Protons, which are positively charged. The other particles that are in a nucleus are Neutrons, but Neutrons are not charged, Neutrons don't have a charge.
What is a particle of alpha?
Alpha particles are positively charged. They have low penetrating power but high ionizing power.
When a beam of alpha particles passes between two electrically charged plates which plate is the beam deflected toward?
The beam of alpha particles is deflected toward the negatively charged plate. This is because alpha particles are positively charged, and opposite charges attract each other.
What are alpha rays attracted to?
Magnetic fieldsNegatively charged objects
Why did the path of only some alpha particles deviate in Rutherford experiment?
Alpha particles are positively charged helium nuclei. As such, they are repelled by other positively-charged nuclei. In Rutherford's experiment, he used gold foil. Since gold atoms have large, massive nuclei, the alpha particles were easily repelled by the large gold atom nuclei, and they were scattered in different directions.
In Rutherfords gold foil experiment shown in Figure 4-1 alpha particles that bounce straight back from the foil have struck in the gold atoms?
No, they struck the nucleus of the atom. Since the alpha particles are positively charged and nucleus is positively charged as well, they repelled each other and alpha particles are repelled back
