What is a Lewis Structure?

Back

A Lewis Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Front

What does a single line represent in a Lewis Structure?

Back

A single line represents a single bond, which indicates that two electrons are shared between two atoms.

Front

How many valence electrons does Boron (B) have?

Back

Boron has 3 valence electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons, achieving a stable electron configuration.

Front

How many valence electrons does Fluorine (F) have?

Back

Fluorine has 7 valence electrons.

Front

What is the correct Lewis structure for BF3?

Back

The correct Lewis structure for BF3 shows Boron in the center with three single bonds to three Fluorine atoms, and no lone pairs on Boron.

Front

What is the Lewis structure for F2?

Back

The Lewis structure for F2 shows two Fluorine atoms connected by a single bond, with three lone pairs of electrons on each Fluorine.

Front

How many electrons does each line in a Lewis structure indicate are shared?

Back

Each line indicates that 2 electrons are shared.

Front

How many electrons does Hydrogen need to be stable?

Back

Hydrogen needs 2 electrons in its valence shell to be stable.

Front

What is the Lewis structure for CCl4?

Back

The Lewis structure for CCl4 shows Carbon in the center with four single bonds to four Chlorine atoms, and no double bonds.
