The Lewis structure of CO2 consists of the symbol for carbon, C, connected to two oxygen symbols surrounded by four dots each. The connections are both made with two parallel lines. Each chemical symbol represents one atom.
The lines represent double covalent bonds. Lewis structures are constructed using the octet rule as a guide. Each atom has an outer shell of electrons, called valence electrons, that are shared with other atoms in chemical bonds. Atoms usually favor having eight valence electrons, and they share valence electrons with other atoms in covalent bonds. Carbon has four valence electrons, and oxygen has six. When a carbon atom double bonds with two oxygen atoms, each oxygen atom gains two electrons to create a full octet, and carbon gains four. Lewis structures represent valence electrons that are not involved in covalent bonding using dots.Learn More
The Lewis structure of ICl3 is a drawing or model chemists use to predict the geometry of the molecule. ICl3 is one of the compounds that don't follow the octet rule, as the iodine at the center of this model accepts 10 electrons.Full Answer >
The Lewis structure for xenon trioxide, which is written with the chemical formula XeO3, has an Xe in the center with three sets of radiating double lines leading to three Os. The Xe is bordered by a pair of dots, and each O is bordered by two pairs of dots.Full Answer >
The Lewis structure for boron tribromide is drawn with a B in the center with three lines connecting to three Brs, each of which contains three pairs of dots around it. The B is the symbol for the single boron atom, and the Brs are the symbol for the three bromine atoms in boron tribromide.Full Answer >
The Lewis dot structure for nitrogen dioxide, written with the chemical formula NO2, has an "N" with a single dot at the center and two "Os" with four dots. One "O" is connected to the "N" with two lines, and the other "O" is connected with one line.Full Answer >
