No. The difference between them is that helium atoms have electrons, and alpha particles don't.

Do alpha particles gain energy as they ionize matter?
Yes alpha particles are matter. In fact they are just the nuclei of Helium atoms. That is Helium atoms without their two orbiting electrons. Alpha particles are therefore composed of two neutrons and two protons.
Which term best describes alpha particles?
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.
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.
Do alpha particles gain energy as they ionize matter?
Yes alpha particles are matter. In fact they are just the nuclei of Helium atoms. That is Helium atoms without their two orbiting electrons. Alpha particles are therefore composed of two neutrons and two protons.
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.
Which term best describes alpha particles?
Does alpha decay produce helium atoms?
Yes, alpha decay does produce helium atoms. Alpha decay occurs when a radioactive nucleus emits an alpha particle, which consists of two protons and two neutrons. This combination of particles is the same as a helium atom nucleus, so the resulting particle is a helium atom.
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.
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.
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.
Describe how smoke detectors use alpha particles and what sets off the alarm?
Alpha particles constantly released by americium knock electrons off atoms in the air ionizing the oxygen, nitrogen atoms
Why is alpha radiation are easiest to stop?
Alpha radiation consists of physical particles ... helium nuclei ...with relatively low energy. Beta radiation consists of a stream of electrons ... much smaller than alpha particles. Gamma rays are electromagnetic ... the electromagnetic rays with the highest frequency, the shortest wavelength, and the greatest energy.
What particles or waves given off by atoms undergoing nuclear decay?
alpha decay - fully ionized helium nucleibeta decay - electrons or positrons, and electron neutrinosgamma decay - very high energy photons
Which forms of radiation are never able to penetrate the Earth's atmosphere?
The major types of radiation are: 1. alpha particles, which are free electrons. 2. beta particles, which are the nuclei of helium atoms 3. gamma rays, which are high-energy electromagnetic radiation like sunlight or X-rays. Alpha and Beta particles are deflected and absorbed by the atmosphere.
What happens to an atom when it emits an alpha particle?
An alpha particle is a helium-4 nucleus. When it captures a pair of electrons, it becomes a helium-4 atom. Alpha particles released in nuclear decay events quickly pick up a pair of electrons from the environment and become those helium atoms, and the atom is said to be electrically neutral.
