Alpha particles are helium nuclei. They don't change, per se, when they "pick up electrons", they just become non-ionic, and their charge becomes zero. They were, and become, so to speak, plain helium.
HELIUM!
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.
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.

HELIUM!
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.
An alpha particle itself is not radioactive, but it is the result of a type of radioactive decay called (obviously) alpha decay. The alpha particle is actually a helium-4 nucleus, and it will eventually pick up a pair of electrons and become an atom of that inert or noble gas.

They have a RAVE, BABY!
It is used in smoke detectors as it cannot travel far in air. Alpha radiation is emitted and as long as the detector in the device is receiving the alpha radiation, then no smoke is present. When smoke particles are present, they interrupt the radiation, and so the detector doesn't pick up the radiation, causing the alarm to go off.
The nucleus of a helium-4 atom is an alpha particle. When an alpha particle, which is two protons and two neutrons, is released in nuclear decay (alpha decay), it will zip out with a lot of kinetic energy. But it will quickly slow down and pick up a pair of electrons from the environment and "become" a 24He atom.
hydrogen ions
A magnet can pick up tiny iron particles that are in sand.
Smoke particles pick up a negative charge.Smoke particles are attracted to the collecting plates.Collecting plates are knocked to remove the smoke particles.
