How many protons neutrons and electrons does bromine 81?
How many protons neutrons and electrons does bromine 81?
35+n=80 to solve for n subtract 35 from both sides. So Bromine Br−1 has 35 protons, 36 electrons and 45 neutrons.
How many protons are in an isotope of Br 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.

Bromine/Symbol
Bromine’s chemical symbol is Br and is part of the halogen group of the periodic table. The bromine substance Br2 is a reddish-brown liquid and is never naturally found in its elemental form but rather in inorganic compounds, also known as bromides, and in natural organo-bromine compounds.

How is bromine 79 and bromine 81 different?
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 colour of bromine at low temperature?
The colour fades at low temperatures, so that solid bromine at −195 °C is pale yellow. Like solid chlorine and iodine, solid bromine crystallises in the orthorhombic crystal system, in a layered lattice of Br 2 molecules.
What are the effects of bromide on the central nervous system?
As a pharmaceutical, the simple bromide ion (Br −) has inhibitory effects on the central nervous system, and bromide salts were once a major medical sedative, before replacement by shorter-acting drugs. They retain niche uses as antiepileptics .
How many electrons are in the outer shell of bromine?
Bromine has the electron configuration [Ar]4s 2 3d 10 4p 5, with the seven electrons in the fourth and outermost shell acting as its valence electrons. Like all halogens, it is thus one electron short of a full octet, and is hence a strong oxidising agent, reacting with many elements in order to complete its outer shell.
