What does bromine decay into?
What does bromine decay into?
The longest decaying fission product is a bromine isotope (Br-87) which has a 55.72 sec half-life (decay constant) for beta decay into stable isotopes of Sr-87 and Kr-86.
What is the isotope for Br?
Bromine (35Br) has two stable isotopes, 79Br and 81Br, and 32 known radioisotopes, the most stable of which is 77Br, with a half-life of 57.036 hours.
How do you find the isotopes of bromine?
Add up the number of protons acquired from Step 3 and the number of neutrons to calculate the mass number of bromine. For this bromine isotope, the mass number is 35 + 46 or 81.
What is the most common isotope of bromine?
Br-79
Most common isotopes: Br-79 (50.7 percent of natural abundance), Br-81 (49.3 percent of natural abundance.
What is the difference between bromine 79 and bromine 81?
The atomic mass of bromine (Br) is 79.90. There are two main isotopes at 79 and 81, which average out to the 79.90amu value. The 79 has 44 neutrons and the 81 has 46 neutrons. While it won’t change the average atomic mass, scientists have made bromine isotopes with masses from 68 to 97.

What is the RAM of bromine?
We say that the relative atomic mass of bromine is 80. This also tells us there is equal proportions of Bromine isotopes as 80 is in the middle of 79 and 81. The relative atomic masses of most elements are not whole numbers because of the existence of isotopes.
What is the relative abundance of 79 Br and 81 Br isotopes?
Bromine has two naturally occurring isotopes (Br-79 and Br-81) and an atomic mass of 79.904 amu. The mass of Br-81 is 80.9163 amu, and its natural abundance is 49.31%.
