Nuclear Reactions Flashcards
Gamma decay emits energy but no particles.
True
An alpha particle is the equivalent of a Helium-4 nucleus.
True
Nuclear decay can change one element into another one.
True
Which has a charge of +1?
Protons
Most of the isotopes which occur naturally are stable
True
A few naturally occurring isotopes and all of the man-made isotopes are unstable.
True
Unstable isotopes can become stable by releasing different types of particles.
True
A particle is a fast moving electron which is emitted from the nucleus of an atom undergoing radioactive decay
beta
particle is identical to that of a helium nucleus and contains two protons and two neutrons
Alpha decay
occurs when a neutron changes into a proton and an electron
Beta decay
the nucleus has one less neutron, but one extra proton
Beta decay
The atomic number, Z, increases by 1 and the mass number, A, stays the same
Beat decay
Unstable isotopes can become stable by releasing different types of particles
radioactive decay: alpha, beta, gamma
