Summative Flashcard 11/20

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

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

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding.

Front

What is the correct electron configuration for Carbon?

Back

1s2 2s2 2p2

Front

Why are noble gases generally unreactive?

Back

Noble gases are generally unreactive because they have a complete valence shell, fulfilling the octet rule.

Front

What is the dot diagram for oxygen (O)?

Back

The dot diagram for oxygen shows 6 valence electrons, typically represented as two pairs and two single electrons.

Front

What is the difference between covalent and ionic bonds?

Back

Covalent bonds involve the sharing of electron pairs between atoms, while ionic bonds involve the transfer of electrons from one atom to another.

Front

What is the molecular formula for Sodium Chloride?

Back

NaCl

Front

What is the significance of valence electrons?

Back

Valence electrons determine how an atom can bond with other atoms and are crucial for chemical reactivity.

Front

What is the Lewis dot structure for fluorine (F2)?

Back

The Lewis dot structure for F2 shows two fluorine atoms, each with 7 valence electrons, sharing one pair of electrons.
