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. Nitric acid is composed of three elements. One is hydrogen, and the other two elements are nitrogen and oxygen.<\/p>\n\n\n\n

The valence electrons of\u00a0nitric acid are the sum of the\u00a0total\u00a0valence\u00a0electrons of\u00a0hydrogen<\/a>, nitrogen<\/a>,\u00a0and\u00a0oxygen<\/a>\u00a0in the compound HNO3<\/sub>. The nitric acid compound has a total of twenty-four electrons in the last\u00a0orbits of hydrogen<\/a>, nitrogen,\u00a0and oxygen.<\/p>\n\n\n

Hence, the total number of valence electrons in nitric acid is twenty-four. 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 nitric acid 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 HNO3<\/sub>?<\/h2>\n\n\n\n

The symbol form of nitric acid is HNO3<\/sub>. To determine the valence electrons of HNO3<\/sub>, it is first necessary to know the valence electrons of the hydrogen<\/a>, nitrogen<\/a>, and oxygen<\/a> atoms.<\/p>\n\n\n\n

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

Step 1: Determine the valence electrons of hydrogen, nitrogen, and oxygen atoms<\/h3>\n\n\n\n

The atomic number of hydrogen is 1. So its total number of electrons is one. The electron configuration<\/a> of hydrogen shows that it has an electron 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 hydrogen are one.<\/p>\n\n\n\n

On the other hand, the atomic number of nitrogen<\/a> is 7. So its total number of electrons is seven.<\/p>\n\n\n

\n
\"valence

The electron configuration of nitrogen<\/a> shows that it has five electrons in its last orbit. Therefore, the valence electrons of nitrogen are five. Again, the atomic number of oxygen<\/a> is 8. So its total number of electrons is eight.<\/p>\n\n\n

\n

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

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

Nitric acid is a compound. It is composed of one hydrogen atom, one nitrogen atom, and three oxygen atoms.<\/p>\n\n\n\n

Therefore, adding the valence electrons of one hydrogen atom, one nitrogen atom, and three oxygen atoms can easily determine the valence electrons of nitric acid.<\/p>\n\n\n\n

From the above mathematical analysis, we can see that the total number of electrons in the outermost orbit of HNO3<\/sub> is twenty-four. Therefore, the valence electrons of HNO3<\/sub> are twenty-four.<\/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
