How many protons electrons and neutrons are in bromine 81?
We are asked to identify the number of protons, neutrons, and electrons in a neutral atom. Additionally, the charge should be on the top right for ions. The number of protons, neutrons, and electrons in 8135Br are 35, 46 and 35 respectively.
What is the number neutrons in 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.
What are protons neutrons and electrons bromine?
The mass number = protons + neutrons. Bromine has a mass number of 80 and 35 protons so 80-35 = 45 neutrons. The neutral atom of bromine has 35 electrons because the number of electrons equals the number of protons.
How many protons electrons and neutrons are in an atom of bromine 80?
ANSWER: There are 35 protons, 45 neutrons, and 35 electrons in 80Br.
What isotope has 81 protons?

What is the mass of bromine 81?
80.9163 amu
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%.
How many protons neutrons and electrons are in bromine 79?
Bromine has an atomic number of 35, and so has 35 protons. You are told that the mass number is 79, and so there are a total of 79 protons plus neutrons….Protons, neutrons and electrons.
| relative mass | relative charge | |
|---|---|---|
| electron | 1/1836 | -1 |
What is bromine number of electrons?
Bromine atoms have 35 electrons and the electronic shell structure is [2, 8, 18, 7] with Atomic Term Symbol (Quantum Numbers) 2P3/2. Atomic Number. 35. Number of Electrons (with no charge)
What does the number 80 mean in bromine-80?
the mass # 80, it means the sum of the number of neutrons and protons in an atomic nucleus.
How many neutrons does bromine 82 have?
So Bromine Br−1 has 35 protons, 36 electrons and 45 neutrons.
How many electrons does BR-81 have?
In a neutral atom the number of protons = the number of electrons. 35 protons = 35 electrons. But Bromine anion with a charge of -1 has one extra electron so 35 +1 = 36 electrons.
How many protons are in bromine?
35

What are protons and neutrons called?
Neutrons and protons, commonly called nucleons, are bound together in the dense inner core of an atom, the nucleus, where they account for 99.9 percent of the atom’s mass. Developments in high-energy particle physics in the 20th century revealed that neither the neutron nor the proton is a true elementary particle; rather,…
