Inquiry Activity: Drawing Lewis Structures for Compounds

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

How many valence electrons does chlorine have?

Back

Chlorine has 7 valence electrons.

Front

What does a 3+ charge on aluminum indicate?

Back

It indicates that aluminum has lost 3 electrons.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

How many bonding pairs are in a triple bond?

Back

There are three bonding pairs in a triple bond.

Front

What is the purpose of a Lewis structure?

Back

A Lewis structure visually represents the valence electrons and bonding in a molecule.

Front

Why are Lewis structures preferred over Bohr models for visualizing chemical bonds?

Back

Lewis structures provide a clearer representation of valence electrons involved in bonding.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds until they are surrounded by eight valence electrons.

Front

What is a lone pair of electrons?

Back

A lone pair of electrons is a pair of valence electrons that are not shared with another atom.

Front

What is the significance of the nucleus in an atom?

Back

The nucleus contains protons and neutrons and is the center of an atom, determining its mass and identity.
