Unit 6 - Lewis Dot Structures

Front

What is a Lewis Dot Structure?

Back

A Lewis Dot 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

Which atom will never be in the middle of a Lewis Dot structure?

Back

Hydrogen (H) will never be in the middle of a Lewis Dot structure.

Front

What is the correct formula for silicon tetrafluoride?

Back

SiF₄

Front

How many valence electrons does carbon have?

Back

Carbon has 4 valence electrons.

Front

How many electrons should Fluorine have around its Lewis dot model?

Back

Fluorine should have 7 electrons around its Lewis dot model.

Front

What does each line in a Lewis Structure represent?

Back

Each line in a Lewis Structure represents 2 electrons.

Front

What is the molecular structure of carbon dioxide (CO₂)?

Back

The molecular structure of carbon dioxide (CO₂) is linear with a double bond between carbon and each oxygen.

Front

What is the significance of lone pairs in Lewis Dot Structures?

Back

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

Front

How do you determine the central atom in a Lewis Dot Structure?

Back

The central atom is usually the least electronegative atom or the atom that can form the most bonds.

Front

What is the octet rule in relation to Lewis Dot Structures?

Back

The octet rule states that atoms tend to bond in such a way that they have 8 electrons in their valence shell.
