The energy is called nuclear radiation, high energy particles and rays that are emitted by the nuclei of some atoms.

That ability is called radioactivity. Atoms with unstable nuclei emit high-energy particles or rays, such as alpha and beta particles or gamma rays, in order to become more stable. This process is known as radioactive decay.
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.
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.

radioactive
No. Molecules don't have a collective nucleus, although the atoms that compose the molecule have their own nuclei.
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).

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.
The collective name for protons, neutrons, and electrons is "subatomic particles." These are the building blocks of atoms and are responsible for their structure and properties.
These atoms are isobars.
A mixture of subatomic particles, nuclei, and electrons describes the composition of atoms. Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons orbiting at various energy levels. The interactions between these particles create the chemical and physical properties of different elements.
protons and neutrons (note: only 1H1 isotope doesn't have neutrons)
No. The difference between them is that helium atoms have electrons, and alpha particles don't.
