Radioactive Decay- Mindmap
- Alpha Decay
- Decreases the charge
and the mass of the
nucleus
- When the nucleus gives out
an Alpha particle, it loses two
protons and two nutrons.
- This means the mass
number decreases by 4
and the atomic number
decreases by 2.
- Decreases the charge
and the mass of the
nucleus
- Beta-minus decay
- Increases the charge of the nucleus
- A neutron becomes
a proton and an
electron
- The mass number doesn't
change and the atomic number
increases by one.
- Increases the charge of the nucleus
- Beta-plus decay
- Decreases the
charge of the
nucleus.
- A proton becomes a
neutron and a positron.
- The mass number
doesn't change and the
atomic number
decreases by 1.
- Decreases the
charge of the
nucleus.
- Neutron
- Decreases the mass
of the nucleas
- The nucleus emits a
neutron
- This means the mass number
decreases by 1 but the atomic
number stays the same.
- Decreases the mass
of the nucleas
- Gamma Rays
- Don't change the charge or
mass of the nucleus.
- A way to get rid of excess
energy. The nucleus goes
from an excited state to a
more stable state.
- The mass and atomic
number stay the same
after a gamma ray has
been emitted.
- Don't change the charge or
mass of the nucleus.
