A neutral atom could become a positively charged particle through the loss of what?
A neutal atom could become a positively charged particle through the loss of an electron.
Why does a beta particle have a negative charge?
A beta particle has an electric charge of -1 because beta particles are both lightweight and fast moving, they have a greater penetrating power than alpha particles.
How did Rutherford know the nucleus was positively charged?
the nucleus is positively charged because it bounces right off of the gold foil
The nucleus is positively charged?
Yes. The atomic nucleus is positively charged because it contains protons which are positively charged subatomic particles.
When a charged rod is repelling a copper ball is the rod positively charged?
yes, because usually metals are positively charged and positive repells positive
Why is an alpha particle attracted to a negative plate?
Alpha particles are deflected towards negative plates because they are positively charged.
What has the least penetrating power gamma ray alpha particle or beta particle?
The gamma ray because a photon does not have electric charge and is thus does not experience force in a EM field. All the others are charged particles
A neutral atom could become a positively charged particle through the loss of what?
A neutal atom could become a positively charged particle through the loss of an electron.
Why is H plus just a proton?
H+ is just a proton because it has lost its one and only electron. In the context of chemistry, a proton is a positively charged particle found in the nucleus of an atom. When an atom loses an electron, it becomes positively charged and is referred to as a proton.
Which subatomic particle has the weakest charge?
I would say a neutrino, because its charge is zero. ------------------------------------------------------------------------ Neutrino is not considered as a subatomic particle. Proton (positively charged) and electron (negatively charged) have very small electrical charge.
Why gold or tungsten used for particle gun method?
"Because the likelihood of a subcellular-sized particle penetrating a cell is proportional to the kinetic energy of the particle, materials of high density have generally been preferred for use in biolistic technology. These compounds include tungsten, platinum, and gold. Of these, gold is favored because it is biologically inert and because spherical gold particles can be produced in a narrow size range."
Why does a beta particle have a negative charge?
A beta particle has an electric charge of -1 because beta particles are both lightweight and fast moving, they have a greater penetrating power than alpha particles.
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 the Example of a proton and neutron?
A proton is a positively charged particle in the center of an atom. A neutron is another particle in the center of an atom that has no charge, but still has mass. Each particle, sometimes called a subatomic particle, has a mass of one AMU. The sum of these is the mass of one atom of an element. Electrons, the particles orbiting the nucleus, where protons and neutrons reside, are not taken into account in massing because they are so small.
Why beta has the least penetrating power?
It is not clear what is meant by 'beta'. Please rephrase it in a new question. It's pretty obvious this question is about radioactivity and the beta particles produced by that. In fact beta particles are not the least penetrating. It is the alpha particles that penetrate least. That's because they interact easily with atomic nuclei. Atomic nuclei are positively charged, like alpha particles, causing strong repulsion.
What does it mean when an atom has more protons then electrons?
When an atom has more protons than electrons it is called an ion. This is a positively charged particle because it has more protons than electrons, thus the positive charge takes over.
Is a ion is a charged particle because it now had either more or fewer electrons than protons?
Yes. If it has fewer electrons that protons, it will be a positively charged ion, and if it has more electrons than protons, it will be a negatively charged ion.
