Carbon-11
* Atomic number: 6 (meaning it has 6 protons)
* Atomic mass: 11 (meaning it has 5 neutrons)
* Isotope: It is a radioactive isotope of carbon, meaning it is unstable and decays over time.
* Half-life: 20.38 minutes.
* Decay mode: Positron emission.
* Uses: Carbon-11 is used in PET (Positron Emission Tomography) scans. It is incorporated into molecules that are used by the body, allowing doctors to see how different organs are functioning.
* Availability: It is produced using cyclotrons, which bombard stable carbon atoms with protons.
Boron
* Atomic number: 5 (meaning it has 5 protons)
* Atomic mass: 10.81 (an average of different isotopes)
* Isotope: Most common boron isotopes are stable (Boron-10 and Boron-11).
* Half-life: Not applicable for the stable isotopes.
* Decay mode: Not applicable for the stable isotopes.
* Uses: Boron is used in a variety of applications, including:
* Glass and ceramics: For its ability to form durable, heat-resistant materials.
* Semiconductors: As a doping agent in silicon for electronic devices.
* BNCT (Boron Neutron Capture Therapy): Certain isotopes of boron are used in a type of cancer treatment.
* Availability: Boron is found naturally in the Earth's crust and is extracted from minerals.
In summary:
* Carbon-11 is a radioactive isotope with a short half-life used in PET imaging.
* Boron is a stable element with various applications including glass, ceramics, semiconductors, and cancer treatment.
