Define Istope
An atom that has the same number of protons as another atoms but a different number of neutrons
1 of 10
What does neutron number to proton number ratio affect?
The stability of an atom's nucleus
2 of 10
The greater the neutron number relative to the proton number...
the more unstable the nucleus
3 of 10
What do unstable nuclei do?
Decay into more stable nuclei
4 of 10
Define Isotopic data
The relative amounts of different isotopes of an element found whithin a substance
5 of 10
Give a use of Isotopic data
To put an age on archaeological finds
6 of 10
In order to estimate the age of a find, what element do araeologists look at
Carbon-14
7 of 10
Why can they use carbon-14 to put an age on fossils?
Most living things have around the same amount of this isotope. It is also radioactive, allowing us to see it decrease over time
8 of 10
What type of matter do archaeologists look for carbon-14 in?
Dead, organic
9 of 10
What does changing the number of neutrons not affect?
An atom's reactivity/chemical properties

Thank you so much! This is the only part of the spec my books missed out.
