Valid Lewis 1 (Easy)

Front

What is an expanded octet?

Back

An expanded octet refers to the ability of certain elements to accommodate more than eight electrons in their valence shell, typically seen in elements from the third period and beyond.

Front

Can sulfur have an expanded octet?

Back

True, sulfur can have an expanded octet.

Front

Can fluorine have an expanded octet?

Back

False, fluorine cannot have an expanded octet.

Front

Can chlorine have an expanded octet?

Back

True, chlorine can have an expanded octet.

Front

Can hydrogen cause an expanded octet?

Back

False, hydrogen cannot cause an expanded octet.

Front

What is a valid Lewis structure?

Back

A valid Lewis structure is a representation of a molecule that satisfies the octet rule for main group elements and shows all 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

Which elements can have an expanded octet?

Back

Elements in the third period and beyond, such as phosphorus, sulfur, and chlorine, can have an expanded octet.

Front

What is the significance of lone pairs in Lewis structures?

Back

Lone pairs represent non-bonding electrons that can affect the shape and reactivity of a molecule.

Front

What is the difference between a single bond and a double bond in Lewis structures?

Back

A single bond involves one pair of shared electrons, while a double bond involves two pairs of shared electrons.
