# How many electrons would you draw in the Lewis dot structure for iodine?

## How many electrons would you draw in the Lewis dot structure for iodine?

12 valence electrons
Iodine is below Period Two on the periodic table so it can have an expanded octet (hold more than eight valence electrons). In the Lewis structure for IF5 you’ll need to put a total of 12 valence electrons on the Iodine atom in order to draw the Lewis structure.

What are electron dot diagrams and how are they drawn?

A Lewis electron dot diagram (or electron dot diagram or a Lewis diagram or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence electrons in the atom.

### Where do you start drawing electrons of an electron dot diagram?

Lewis in 1916. These diagrams are used as a shorthand notation to show the number of valence electrons in an atom. More complicated versions can be used to show the bond between different atoms in a molecule. Write the symbol of the atom you are drawing the electron dot diagram for in the middle of your paper.

How many electrons can iodine have?

53
Iodine has 7 valence electrons and 46 core electrons for a total of 53 , the atomic number.

## What is the electron dot structure of iodine?

Iodine is a halogen with seven valence electrons so you would draw seven dots which two dots on three sides of the iodine molecule and one on one side surrounded by a bracket with a negative sign on the top right corner.

What do electron dot diagrams show us?

Electron dot diagrams are diagrams in which the valence electrons of an atom are shown as dots distributed around the element’s symbol. A beryllium atom, with two valence electrons, would have the electron dot diagram below. Since electrons repel each other, the dots for a given atom are distributed evenly around the symbol before they are paired.

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

Electron dot diagrams, sometimes called Lewis dot diagrams, were first used by Gilbert N. Lewis in 1916. These diagrams are used as a shorthand notation to show the number of valence electrons in an atom. More complicated versions can be used to show the bond between different atoms in a molecule.

What do the electrons in an electron dot structure represent?

A Lewis electron dot diagram (or electron dot diagram, or a Lewis diagram, or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence electrons in the atom.
