This means that they will have the same chemical properties (will react the same), but will have different physical properties (eg. Boron isotopes randomly distributed within the crystal structure scatter the phonons modes more frequently and reduce their lifetime. The neutrons are almost exclusively absorbed by boron-10. In this regard, two research groups have suggested that using boron isotopes will lead to a radiation effectiveness enhancement, using boron-11 agent to initiate the proton fusion reaction. So the difference between boron 10 and boron 11 is that boron 10 has one less neutron than boron 11, or, equally, boron 11 has one more neutron than boron 10. Crystals that contain only boron-10 (h 10 BN) or boron-11 (h 11 BN) have longer phonon lifetimes. Boron-10 is administered to the cancerous cells and then the body is bombarded with slow neutrons.
This means that in Carbon 14, there are still 6 protons and 6 electrons (we know this as it is still carbon hence still has 6 protons, and is still neutral hence still has 6 electrons), but there are 8 neutrons. So the difference between boron 10 and boron 11 is that boron 10 has one less neutron than boron 11, or, equally, boron 11 has one more neutron than boron 10. Note that the number is always the mass number. A well known isotope of Carbon 12 is Carbon 14. Carbon 12 has 6 protons, 6 neutronsand 6 electrons. thermal neutron, whereas, Boron-11 is almost immune to radiation damage (Han et al. This means that the atomic number (proton number: in boron's case this is 5) is the same (which is good, as it's the number of protons which determines what element is which), but the mass number will be different.įor example. Boron-10 (10 B) and Boron-11 (11 B) are the two stable isotopes of Boron (B).Naturally found Boron consists of 20 of boron-10 (10 B) and 80 of boron-11 (11 B).Boron-10 is sensitive to nuclear radiation e.g. The boron in the Periodic Table has an atomic weight of 10.8, which is basically the average of all of boron's isotopes' atomic weights.Īn isotope is an atom of an element with the same number of protons, but a different numberof neutrons. For starters they are both isotopes of Boron.
