==Key Stage 4==
===Meaning===
[[Isotope]]s are [[atom]]s with the same number of [[proton]]s (the same [[element]]) but a different number of [[neutron]]s.
===About Isotopes===
: Each [[element]] has many [[isotope]]s but some are [[Stable Isotope|stable]] and others are [[Unstable Isotope|unstable]] so they [[Radioactive Decay|decay]] quickly into other [[isotope]]s or a different [[element]].
: Different [[isotope]]s of the same [[element]] have the same [[Atomic Number|atomic number]] but different [[Relative Atomic Mass|atomic mass]] due to the different numbers of [[neutron]]s.
