What is the electron configuration of the bromide ion?
The electron configuration of bromide ion (Br –) is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6. The electron configuration of bromide ion (Br –) shows that the bromide ion acquired the electron configuration of krypton. Bromine atom exhibit -1, +1, +3, +5 oxidation states. The oxidation state of the element changes depending on the bond formation.
Why does a monatomic bromine have 7 valence electrons?
Chemical elements need 8 electrons (stable octet rule) in their outer energy level (valence shell) to become energetically stable. A monatomic bromine has 7 valence electrons so it interacts with itself and shares electrons (covalent binding) to end up with 8 electrons around each atom. This is the reason why bromine floats around as a diatom.
How many electrons does I need to be stable?
eight electronsMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to 18 electrons.
Does bromine have a stable shell?
Like the other halogens, bromine has seven electrons in its outer shell and is very reactive. You will find bromine in many salt compounds with alkali metals. Sodium bromide is a compound found in seawater. As with all reactive elements, bromine is never found alone in nature.

How many pairs of valence electrons does Br have?
The answer is B) 3.
How many electrons will bromine gain in forming an ion?
one electronFor example, the neutral bromine atom, with 35 protons and 35 electrons, can gain one electron to provide it with 36 electrons. This results in an anion with 35 protons, 36 electrons, and a 1− charge. It has the same number of electrons as atoms of the next noble gas, krypton, and is symbolized Br−.

Why is bromine very reactive?
Bromine is a very chemically reactive metal and thus is never pure in nature: due to its 7 valence electrons and high electron affinity, bromine reacts readily, and violently, with the alkali metals.
Protons and Neutrons in Bromine
Bromine is a chemical element with atomic number 35 which means there are 35 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
Electrons and Electron Configuration
The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Bromine is 35. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
Most Common Application of Bromine
Bromine is intermediate in reactivity between chlorine and iodine, and is one of the most reactive elements. A wide variety of organobromine compounds are used in industry. Some are prepared from bromine and others are prepared from hydrogen bromide, which is obtained by burning hydrogen in bromine.
Bromine (Br) electron configuration through orbit
Scientist Niels Bohr was the first to give an idea of the atom’s orbit. He provided a model of the atom in 1913. The complete idea of the orbit is given there. The electrons of the atom revolve around the nucleus in a certain circular path. These circular paths are called orbit (shell). These orbits are expressed by n. [n = 1,2,3,4 .
Electron configuration of bromine (Br) through orbital
The German physicist Aufbau first proposed an idea of electron configuration through sub-orbits. The Aufbau method is to do electron configuration through the sub-energy level. These sub-orbitals are expressed by ‘l’.
How to write the orbital diagram for bromine (Br)?
To create an orbital diagram of an atom, you first need to know Hund’s principle and Pauli’s exclusion principle. Hund’s principle is that electrons in different orbitals with the same energy would be positioned in such a way that they could be in the unpaired state of maximum number and the spin of the unpaired electrons will be one-way.
Bromine (Br) excited state electron configuration
Atoms can jump from one orbital to another orbital by excited state. This is called quantum jump. Ground state electron configuration of bromine is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 5. In the bromine ground-state electron configuration, five electrons of the 4p orbital are located in the 4p x (2), 4p y (2) and 4p z sub-orbitals.
Bromide ion (Br –) electron configuration
The electron configuration of bromine shows that the last shell of bromine has seven electrons. Therefore, the valence electrons of bromine are seven. The elements that have 5, 6, or 7 electrons in the last shell receive the electrons in the last shell during bond formation. The elements that receive electrons and form bonds are called anions.
How many valence electrons does bromine have?
Bromine has an atomic number of 35 and an atomic mass of 79.904 g/mol. It is a member of the halogen family in group 17, which means it is in the same column as fluorine, chlorine, and iodine on the periodic table.
What is the electron configuration for bromine?
If you are interested in the electron configuration for bromine, then this is the post for you. Bromine is a reactive element that reacts with hydrochloric acid to produce hydrogen gas and hydrobromic acid. It also reacts with metals like magnesium to form metal bromide salts.
How do you find valence electrons?
Valence electrons are the outermost electron in an atom, and they determine what type of element it is. To find valence electrons, start by drawing a picture of the atoms that make up the molecule. Next, color each nucleus with one or more colors to represent protons and neutrons.
How many neutrons does bromine have?
Bromine is a chemical element with the atomic number 35 and belongs to group 17 of the periodic table. Bromine has 35 protons, so it also has an equal number of electrons. The bromine atom’s most common isotopes are Br-79 (35 neutrons) and Br-81 (37 neutrons).
How many protons do bromine have?
Did you know bromine has two neutrons? It’s true! If that doesn’t sound like a lot, then here is a fun fact: it takes about 100 protons to make up a single neutron. That means bromine atoms have 98 more electrons than protons.
