What else can I help you with?
Do alpha particles gain energy as they ionize matter?
Yes, alpha particles gain energy as they ionize matter because they transfer energy to the atoms they interact with. This energy is used to ionize the atoms by liberating electrons from their orbit, creating positively charged ions.
Can particles leave the atom?
Yes. This process is called radioactive decay. The primary particles emitted are alpha particles, which are helium-4 nuclei, and beta particles, which are electrons.
In Rutherfords experiment why wouldn't the electrons in the atoms of the gold foil affect the paths of the alpha particles?
Electrons are so small that they have no affect. The alpha particles were 2 protons and 2 neutrons being shot thru, even though the electrons have a negative charge..they are so small and take up so little space, the alpha particles probably n ever even came near them.
Does helium have smaller particles than nitrogen or oxygen?
Helium has smaller particles than nitrogen or oxygen. Helium atoms are smaller in size, as they have fewer protons and neutrons in their nucleus compared to nitrogen or oxygen atoms. This smaller size allows helium atoms to move more freely and escape into the atmosphere, which is why helium is a lighter gas.
Scientists who discovered protons?
Protons were discovered when the nucleus of atoms were discovered. Electrons were already known about, so when the nucleus was discovered, it was known that it had to contain positively charged particles: protons. The nucleus was discovered by Ernest Rutherford by shooting alpha particles (helium nuclei, basically helium without the electrons) at a thin sheet of gold. Most of the alpha particles went straight through, but some if them were scattered. Rutherford deduced that these particles had hit something in the foil that didn't take up a large percentage of space: the nuclei of the gold atoms.
When alpha particles pick up electrons they become?
When alpha particles pick up electrons, they become helium atoms. Alpha particles are essentially helium nuclei without electrons, so when they pick up electrons, they form stable helium atoms with a balance of protons and electrons.
Do the alpha particles in Rutherford's experiment contain electrons?
No, alpha particles are helium nuclei made up of two protons and two neutrons, with no electrons. In Rutherford's experiment, alpha particles were used to probe the structure of atoms by scattering off the positive nucleus, helping to reveal the atom's structure.
Do alpha particles gain energy as they ionize matter?
Yes, alpha particles gain energy as they ionize matter because they transfer energy to the atoms they interact with. This energy is used to ionize the atoms by liberating electrons from their orbit, creating positively charged ions.
Is helium a product of radioactive decay?
Yes. Alpha particles can be a product of radioactive decay, and alpha particles are simply Helium nuclei. Unless they interact with other atoms, they will tend to pick up stray electrons (they need two) and become stable 4He atoms.
Where to find helium atoms to make a balloon float?
you can use alpha particles from a cyclotron to get helium nucleuses, then you need to get some electrons from a cathode ray tube, and then you need to put the electrons around the nucleus. This is the most tedious part.
Does alpha decay produce helium atoms?
Technically it produces helium nuclei. Eventually these can pick up electrons and turn into helium atoms, so the answer to the question could be either yes or no depending on how picky you want to be.
Why is helium mixed with radioactive minerals?
Helium is produced as a byproduct of radioactive decay in minerals like uranium and thorium. These minerals contain alpha particles, which are essentially helium nuclei. As these alpha particles are emitted during decay, they capture electrons from their surroundings to become helium atoms. This is why helium is often found mixed with radioactive minerals.
How is the relationship between protons and alpha particles similar to the relationship between beta particles and electrons?
An Alpha Particle is a fast, bare Helium nuclei composed of two protons, two neutrons, and no electrons, that is ejected at high velocity from a decaying nuclei. A Beta Particle is an electron or positron, ejected at extremely high velocity from a decaying nuclei. Both alpha particles and protons are Bosons. Both beta particles and electrons are Leptons. Their relationships are similar because the electron and proton are both components of atoms. The beta and alpha particles are both fragments ejected from decaying atoms.
Are gold atoms similar to alpha particles?
An alpha particle is the nucleus of a Helium-4 atom; therefore, it has 2 neutrons and 2 protons. A gold atom has... well, much more protons and neutrons, you can look it up if you like. Also, a gold atom normally does have electrons, whereas an alpha particle is just the nucleus (i.e., no electrons). You decide for yourself how "similar" those two are.
Is alpha radiation a ionization radiation?
Yes, alpha radiation is a form of ionizing radiation. It consists of alpha particles, which are helium nuclei composed of two protons and two neutrons. These particles have high energy and can ionize atoms by knocking off electrons from them as they pass through matter.
What types of atoms realease nuclear radiation?
Atoms with unstable nuclei, such as uranium, radium, and plutonium, can release nuclear radiation. This radiation can take the form of alpha particles (helium nuclei), beta particles (electrons or positrons), or gamma rays (high-energy photons).
Are gold and helium both made of subatomic particles?
Yes, both gold and helium are made of subatomic particles. Gold is composed of atoms containing protons, neutrons, and electrons, while helium is a noble gas made up of atoms with two protons, two neutrons, and two electrons.
