the mass # 80, it means
the sum of the number of neutrons and protons in an atomic nucleus
How many protons does Br-80 have?
Bromine has
35 protons
and a mass number of 80.
What is the isotope symbol for bromine-80?
Bromide ion
Br-
80 | Br- – PubChem.
How many neutrons does the isotope of bromine-80 have?
The isotopic mass is the MASS of the massive nucular particles. We gots a bromine atom, so we KNOW that there are 35 protons, 35 massive, positively charged nuclear particles. But the 80Br nucleus must manifestly contain
45 neutrons
to give this isotope.
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 highest energy level for bromine?
- First Energy Level: 2.
- Second Energy Level: 8.
- Third Energy Level: 18.
- Fourth Energy Level: 7.
What is the most common isotope of bromine?
