Which of the following is the correct electron configuration for the bromide ion Br -?
Re: Electron Configuration for Br- (Bromide ion) The electron configuration for Br- would be [Br] 4s2 3d10 4p6 and not [Kr] because with an extra electron the Bromine atom does not become Krypton. It would retain the same number of protons but just have an extra electron.
Is bromide A BR?
A bromide ion is the negatively charged form (Br−) of the element bromine, a member of the halogens group on the periodic table.
Why does BR have 7 valence electrons?
Valency of bromine is 1. It is determined by the number of valence electrons in the outermost shell of the element. Bromine has atomic number 35, which means it has 7 electrons in its valence shell. It needs one more electron to attain the noble gas configuration.
How many electron does magnesium have?
The most common and stable type of magnesium atom found in nature has 12 protons, 12 neutrons, and 12 electrons (which have a negative charge).
Is bromide A Br?
How many electrons do Br have?
35 electrons
The atomic number for bromine is 35, which means it has 35 protons in its atomic nuclei. A neutral bromine atom would also have 35 electrons.
Why is bromine bad for you?
Breathing bromine gas could cause you to cough, have trouble breathing, get a headache, have irritation of your mucous membranes (inside your mouth, nose, etc.), be dizzy, or have watery eyes. Getting bromine liquid or gas on your skin could cause skin irritation and burns.
What is the most common ion for bromine?
Bromide is a halide anion and a monoatomic bromine….What is the most common ion formed by bromine?
| Element Name | Bromine |
|---|---|
| Atomic Number | 35 |
How many electrons does magnesium bromide take in its valence?
Actually,bromine takes one electron in its valence shell to achieve the electronic configuration of inert gas. Now put two ions (Mg2+ Br-) side by side. Now we need to balance positive and negative charge.To balance 2+ of magnesium ,we need two bromide.
How many electrons does a bromine ion have?
When Bromine forms an ion it gains one valence electrons. Since electrons are negative, gaining one electron results in Br having a 1- charge. To write the electron config all we have to do is add one electron to the configuration for Br. That leaves us with: And that is the electron configuration for Br- , the Bromide ion.
Which is the chemical symbol for magnesium bromide?
The chemical symbol for magnesium is Mg.Besides,Mg is an element of group (II ) in the periodic table.Thus,Mg releases two electron and it becomes Mg2+ ion to achieve the electronic configuration of inert gas.Here the oxidation number of Mg is +2.
Is the electron configuration of bromine the same as argon?
We’ll also look at why Bromine forms a 1- ion and how the electron configuration for Br- is the same as the Nobel gas Argon. To begin with, Bromine (Br) has an electronic configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5. To learn more about writing electron configurations see:
