# Electron Dot Diagrams: Stumped on CN?

• kristina
In summary, an electron dot diagram, also known as a Lewis dot diagram, is a visual representation of the valence electrons in an atom. To draw one, you need to determine the number of valence electrons an atom has and place dots around the element's symbol. The purpose of an electron dot diagram is to show the arrangement of valence electrons and help understand the properties of elements. The number of valence electrons for an element can be found by looking at its group number on the periodic table. An example of an electron dot diagram for CN would have 4 valence electrons for carbon and 5 valence electrons for nitrogen, shown as dots arranged in a specific pattern.

how would the electron dot diargram for CN look? i am tired and stumped.

Are you sure you don't mean CN-, the cyanide ion which is C tripple bonded to N?

kristina, we expect posters to have shown some effort before we respond to schoolwork problems.

Cesium, please keep the above in mind.

## 1. What is an electron dot diagram?

An electron dot diagram, also known as a Lewis dot diagram, is a visual representation of the valence electrons in an atom. It uses dots to represent the valence electrons and shows how they are arranged in an atom's outermost energy level.

## 2. How do you draw an electron dot diagram?

To draw an electron dot diagram, you first need to determine the number of valence electrons an atom has. This can be found by looking at the group number of the element on the periodic table. Then, you draw the element's symbol and place one dot for each valence electron around the symbol, starting at the top and going clockwise.

## 3. What is the purpose of an electron dot diagram?

The purpose of an electron dot diagram is to show the arrangement of valence electrons in an atom. This can help in understanding the chemical and physical properties of elements and how they bond with other atoms to form molecules.

## 4. How do you determine the number of valence electrons for an element?

The number of valence electrons for an element can be found by looking at its group number on the periodic table. Elements in the same group have the same number of valence electrons. For example, all elements in group 1 have 1 valence electron, while elements in group 14 have 4 valence electrons.

## 5. Can you show an example of an electron dot diagram for CN?

Yes, the electron dot diagram for CN would have 4 valence electrons for carbon (C) and 5 valence electrons for nitrogen (N). The dots would be arranged as follows:
