Answer :
Nitrogen-16 is a radioactive isotope of nitrogen, and its emission properties depend on the type of decay it undergoes. Nitrogen-16 can undergo beta-minus decay, where a neutron is converted into a proton, emitting an electron and an electron antineutrino. The emitted electron, also known as a beta particle, has a negative charge.
In air, the beta particles emitted by Nitrogen-16 can have a range of distances traveled depending on their initial energy. Higher-energy beta particles have longer ranges compared to lower-energy ones. In general, beta particles can travel a few centimeters to a few meters in air before losing most of their energy through ionization and excitation of air molecules.
When passing through iron, the beta particles emitted by Nitrogen-16 will experience interactions with the atomic nuclei and electrons of the iron material. These interactions lead to energy loss through ionization and scattering processes. As a result, the range of beta particles in iron is significantly shorter compared to air. The exact range depends on the initial energy of the beta particle and the density of the iron material. It can range from a few micrometers to a few millimeters.
It's important to note that the range of charged particles can vary based on the initial energy, the material they are passing through, and other factors. The ranges provided here are approximate values to give an idea of the general behavior of beta particles emitted by Nitrogen-16 in air and iron.
