What is the Lewis dot structure for O3?

The Lewis dot structure for O3, the chemical formula for ozone, is written with three Os. The Os in a proper Lewis for ozone are surrounded by dots for each valence electron. Lines that represent bonded pairs of electrons connect the Os.

The Lewis structure for ozone can be drawn more than one way. In one version, the leftmost O is surrounded by two pairs of electrons and is connected to the center oxygen atom by two lines representing a double bond. The center oxygen atom has one pair of dots and a single line connecting it to the O on the right, which contains six additional dots.
