The total number of electrons in the last orbit of an element is called the valence electrons of that element. Two or more elements combine to form compounds.<\/p>\n\n\n\n

The valence electrons of a compound are the sum of the total valence electrons<\/a> of each element in that compound. Bromine difluoride consists of two atoms. One is a bromine atom and the other is a fluorine atom.<\/p>\n\n\n\n

The valence electrons of\u00a0bromine difluoride are the sum of the total valence\u00a0electrons of bromine<\/a>\u00a0and fluorine in the compound BrF2<\/sub>. The bromine difluoride compound has a total of twenty-one electrons in the last\u00a0orbits of bromine<\/a>\u00a0and fluorine.<\/p>\n\n\n

Hence, the total number of valence electrons in bromine<\/a> difluoride is twenty-one. To determine the valence electrons of a compound, the number of valence electrons in each element of the compound must be known.<\/p>\n\n\n\n

This article discusses in detail how to determine the valence electrons of BrF2<\/sub>, BrF2<\/sub>–<\/sup>, and BrF2<\/sub>+<\/sup> very easily. Hopefully, after reading this article you will know more about this topic.<\/p>\n\n\n\n

How to easily determine the number of valence electrons of BrF2<\/sub>?<\/h2>\n\n\n\n

The symbol form of bromine difluoride is BrF2<\/sub>. To determine the valence electrons of BrF2<\/sub>, it is first necessary to know the valence electrons of the fluorine<\/a> and bromine atoms.<\/p>\n\n\n\n

To determine the valence electrons of bromine difluoride we have to follow two steps. It is shown below:<\/p>\n\n\n\n

Step 1: Determine the valence electrons of bromine and fluorine atoms<\/h3>\n\n\n\n

The atomic number of bromine is 35. So its total number of electrons is thirty-five. The electron configuration<\/a> of bromine shows that it has seven electrons in its last orbit.<\/p>\n\n\n

We already know that the electrons in the last orbit of an element are the valence electrons of that element. Therefore, the valence electrons of bromine are seven.<\/p>\n\n\n\n

On the other hand, the atomic number of fluorine<\/a> is 9. So its total number of electrons is nine.<\/p>\n\n\n

The\u00a0electron configuration of fluorine<\/a>\u00a0shows that it has seven electrons in its last orbit. Therefore, the valence electrons of fluorine are seven.<\/p>\n\n\n\n

Step 2: Determine the total number of valence electrons in the bromine difluoride compound<\/h3>\n\n\n\n

Bromine difluoride is a compound. It is composed of one bromine atom and two fluorine atoms.<\/p>\n\n\n\n

Therefore, adding the valence electrons of one bromine atom and the valence electrons of two fluorine atoms<\/a> can easily determine the valence electrons of bromine difluoride.<\/p>\n\n\n\n

From the above mathematical analysis, we can see that the total number of electrons in the outermost orbit of BrF2<\/sub> is twenty-one. Therefore, the valence electrons of BrF2<\/sub> are twenty-one.<\/p>\n\n\n\n

How to determine the valence electrons of BrF2<\/sub>+<\/sup> and BrF2<\/sub>–<\/sup>?<\/h2>\n\n\n\n

The bromine difluoride compound has an unpaired electron. It is shown in the figure above. For this, bromine difluoride can accept or donate an electron.<\/p>\n\n\n\n

BrF2<\/sub>+<\/sup> will have twenty valence electrons while bromine difluoride donates one electron.<\/p>\n\n\n\n

Mathematical Analysis:<\/strong><\/p>\n\n\n\n

BrF2<\/sub>+<\/sup>
= 7 + (7\u00d72) – 1
= 20<\/p>\n\n\n\n

On the other hand, if bromine difluoride accepts one electron, the valence electrons of BrF2<\/sub>–<\/sup> will be twenty-two.<\/p>\n\n\n\n

Mathematical Analysis:<\/strong><\/p>\n\n\n\n

BrF2<\/sub>–<\/sup>
= 7 + (7\u00d72) + 1
= 22<\/p>\n\n\n\n

Why do you need to know the valence electrons of an element?<\/h2>\n\n\n\n

In addition to knowing the number of electrons of an element<\/a>, it is also necessary to know the number of valence electrons of that element. The number of valence electrons of an element carries important properties of that element.<\/p>\n\n\n\n

Many important properties of elements and compounds can be determined by valence electrons. Some important features are mentioned below:<\/p>\n\n\n\n
