TRANSCRIPT
COUNTING THE PARTICLES
L.I.•To describe the nucleus•To use nuclear equations to work out what happens during radioactive decay.
Keywords: •Isotopes•Protons and neutrons•α and β particles
To do: Count the number of particles inside the nuclei of these carbon isotopes.
Carbon-14 isotopeNumber of protons = _________Number of neutrons = _________
Carbon-12 isotopeNumber of protons = _________Number of neutrons = _________
CThe number of particles in the nucleus (protons + neutrons)
146
This is the number of protons
Revision: The nucleus of an atom is described by mass number and atomic/proton number.
C126
How does alpha decay change the nucleus?
To do: Write a nuclear equation for this decay.
During a beta decay, A neutron in the nucleus decays to a proton and an electron (β particle).
