Electron capture is the absorption of an electron by an atomic nucleus if that nucleus is neutron poor. An electron is captured, usually from an inner electron shell of that atom, and it will convert a proton in the nucleus into a neutron. We know that a neutron is converted into a proton and an electron in neutron decay, so it might be looked at as something of an opposite nuclear reaction where a proton and an electron combine to form a neutron.

What is the final result of radioactive decay?
radioactive isotope
Is the atom left after decay often radioactive?
Truw
What is the effect of pressure on the rate of radioactive decay?
Pressure does not affect the rate of radioactive decay. That is entirely unaffected by the environment within the nucleus of the atom.
What is the process of isotopes breaking down and emitting particles such as alpha or beta to form a new substance?
Radioactive decay is the process in which a nucleus of an unstable atom loses energy through ionizing radiation. When this happens, one of its neutrons breaks down into a proton and an electron. The electron then leaves the atom as a beta particle.
What is an unstable nucleus that starts a decay process called?
A nucleus that starts to decay is called a radioactive nucleus or atom. It decays with a known and unique half life by several processes including but not limited to beta decay, alpha decay, electron capture decay, and positron emission.
What is the final result of radioactive decay?
radioactive isotope
What is an atom stable?
An atom is stable if it does not undergo decay.
What is when the nucleus of an atom decomposes called?
radioactive decay
Is the atom left after decay often radioactive?
Truw
When radioactive decay occurs a atom is always produced by the action?
During any type of radioactive decay, one isotope (type of atom) will convert into a different isotope.
When an atom undergoes radioactive decay the energy released in the reaction comes from what?
The energy that comes from the radioactive decay of an atom can come from the electrons and can come from the strong force inside the nucleus.
When an atom undergoes radioactive decay does it become a different element?
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
Can a radioactive element completely decay so that it is all stable matter?
A radioactive element (atom) can decay up to a stable isotope.
What process is a radioactive decay?
The process of a radioactive decay is atomic nucleus of an unstable atom loses energy by emitting ionizing particles
What is the release of a helium atom involved in?
This is the alpha radioactive decay.
Do atom get rid of their excess energy by giving off radioactive decay?
Yes, that's more or less what happens in the case of radioactive decay.
What is the effect of pressure on the rate of radioactive decay?
Pressure does not affect the rate of radioactive decay. That is entirely unaffected by the environment within the nucleus of the atom.
