Why does a beta particle have a negative charge?
A beta particle is an electron or a positron emitted during radioactive decay. Electrons are negatively charged because they have an excess of electrons compared to protons. Positrons are positively charged because they have a deficiency of electrons compared to protons.
A neutral atom could become a positively charged particle through the loss of what?
A neutral atom could become a positively charged particle through the loss of one or more electrons. When an atom loses electrons, it becomes positively charged because there are more protons than electrons in the atom, creating an overall positive charge.
What is a charge on the nucleus of a helium?
A helium nucleus, also known as an alpha particle, has 2 positive charges. This is because the nucleus of a helium atom consists of 2 protons, which are positively charged particles.
How do penetrating and non-penetrating solutes differ in their ability to cross cell membranes?
Penetrating solutes can cross cell membranes easily due to their ability to dissolve in lipids, while non-penetrating solutes cannot cross cell membranes easily because they do not dissolve in lipids.
The nucleus is positively charged?
Yes, the nucleus of an atom is positively charged because it contains positively charged protons. Electrons, which are negatively charged, orbit around the nucleus to maintain the overall neutrality of the atom.
What has the least penetrating power gamma ray alpha particle or beta particle?
Alpha particles have the least penetrating power compared to gamma rays and beta particles. This is because alpha particles are heavier and more positively charged, which makes them easily absorbed by materials, including skin.
Why does a beta particle have a negative charge?
A beta particle is an electron or a positron emitted during radioactive decay. Electrons are negatively charged because they have an excess of electrons compared to protons. Positrons are positively charged because they have a deficiency of electrons compared to protons.

A neutral atom could become a positively charged particle through the loss of one or more electrons. When an atom loses electrons, it becomes positively charged because there are more protons than electrons in the atom, creating an overall positive charge.
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.
Why is an alpha particle attracted to a negative plate?
An alpha particle is made up of two protons and two neutrons, giving it a positive charge. As opposite charges attract, the positive charge of the alpha particle is attracted to the negative charge of the plate.
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."
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.
Is a proton a cation?
Yes, a proton is a cation because it is a positively charged particle. In chemical terms, a cation is an ion with a positive charge, which a proton exhibits due to its positive electric charge.
What subatomic particle is similar to hydrogen ions?
Protons are similar to hydrogen ions because they are positively charged particles found in the nucleus of an atom. Hydrogen ions are just protons that are not associated with an electron.
What is a charge on the nucleus of a helium?
A helium nucleus, also known as an alpha particle, has 2 positive charges. This is because the nucleus of a helium atom consists of 2 protons, which are positively charged particles.
