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.<\/p>\n\n\n\n

Dichloromethane (Methylene chloride, or methylene bichloride) is composed of three elements. One is carbon, and the other two elements are hydrogen and chlorine.<\/p>\n\n\n\n

The valence electrons of\u00a0dichloromethane are the sum of the\u00a0total\u00a0valence\u00a0electrons of carbon<\/a>,\u00a0hydrogen<\/a>,\u00a0and\u00a0chlorine<\/a>\u00a0in the compound CH2<\/sub>Cl2<\/sub>.<\/p>\n\n\n

The dichloromethane compound has a total of twenty electrons in the last orbits of carbon<\/a>, hydrogen, and chlorine.<\/p>\n\n\n\n

Hence, the total number of valence electrons in dichloromethane is twenty. 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 dichloromethane 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 CH2<\/sub>Cl2<\/sub>?<\/h2>\n\n\n\n

The symbol form of dichloromethane is CH2<\/sub>Cl2<\/sub>. To determine the valence electrons of CH2<\/sub>Cl2<\/sub>, it is first necessary to know the valence electrons of the carbon<\/a>, hydrogen<\/a>, and chlorine<\/a> atoms.<\/p>\n\n\n\n

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

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

The atomic number of carbon<\/a> is 6. So its total number of electrons is six. The electron configuration<\/a> of carbon shows that it has four electrons in its last orbit.<\/p>\n\n\n\n

\"Valence

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 carbon are four.<\/p>\n\n\n\n

On the other hand, the atomic number of hydrogen is 1. So its total number of electrons is one.<\/p>\n\n\n

The electron configuration of hydrogen<\/a> shows that it has an electron in its last orbit. Therefore, the valence electrons of hydrogen are one. Again, the atomic number of chlorine is 17. So its total number of electrons is seventeen.<\/p>\n\n\n\n

\"valency

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

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

Dichloromethane is a compound. It is composed of one carbon atom, two hydrogen atoms, and two chlorine atoms.<\/p>\n\n\n\n

Therefore, adding the valence electrons of one carbon atom, two hydrogen atoms and two chlorine atoms can easily determine the valence electrons of dichloromethane.<\/p>\n\n\n\n

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