First of all, let's talk about α, β,
Gamma particle
Alpha particles are
Helium atom
Two are missing.
electron
Helium nucleus needs two electrons because it has lost two electrons.
positive electricity
Beta particles are electrons;
Gamma particles are energetic.
photon
Why not call them directly, but give them some names? This has nothing to do with history.
material
. find
atomic structure
Later, I found out.
radioactivity
This phenomenon was discovered by Alpha at that time.
granule
I didn't know it was a helium nucleus without two electrons, so I named it alpha particle, but it turned out to be a helium nucleus without two electrons. β and γ particles are also found in this way.
Answer below
Your question
：
1.
An alpha particle can capture two electrons and become
electric neutrality
Helium nucleus, but it's best not to say that there are beta particles, so we take it from.
nuclear disintegration
Publish from ...
The electron of
It is called beta rays, or beta particles. Obviously, when a irradiated alpha particle encounters two electrons, it is not necessarily an electron that decays from the nucleus. Therefore, when alpha particles are neutralized, it is more accurate to say that electrons are neutralized.
2.
Alpha particles are not radioactive, so-called radioactivity means releasing alpha, beta or gamma.
element
It's not released radiation particles, okay?
3.
Alpha particles and beta particles are themselves radiation particles, or they are called them.
ray
More precisely, because irradiated particles usually
vitality
, at
Cloud chamber/expansion chamber/fog chamber
or
explorer
Form a ray in.
4.
Yes or no
electric charge
And radiation are two different things.
concept
. Radiation refers to particles (α, β or γ) with high energy and instability, which release radiation through decay or reaction.
