Unit 6 Week 16 (Due 12-8-2024, CLOSES 12/16)

Front

What does the symbol above F in a Lewis structure indicate?

Back

Electrons are more attracted to F than H.

Front

What is the molecular geometry of CF₄?

Back

It has four polar bonds and is a non-polar molecule.

Front

What is the predicted bond angle at the central atom of the azide ion (N₃⁻)?

Back

180°.

Front

Which Lewis dot structure is correct for the molecule fluorine (F₂)?

Back

Structure B.

Front

What happens if you use up all the valence electrons and don't have an octet?

Back

Form double or triple bonds.

Front

Define a Lewis structure.

Back

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

Front

What is a polar bond?

Back

A bond between two atoms where the electrons are not shared equally, resulting in a dipole moment.

Front

What is a non-polar molecule?

Back

A molecule that has an even distribution of charge, resulting in no overall dipole moment.

Front

Explain the octet rule.

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are involved in forming bonds between atoms and determine the chemical properties of an element.
