Understanding Lewis Structures in Ionic Bonding

What is the primary focus of Lewis Structures?

• Hydrogen bonding

• Metallic bonding

• Covalent bonding

• Ionic bonding

In ionic bonding, what happens to electrons?

• They are transferred from metals to non-metals.

• They are shared equally between atoms.

• They are transferred from non-metals to metals.

• They remain with the original atom.

How many valence electrons does sodium have in its Lewis Structure?

• Eight

• One

• Two

• Seven

What is the charge on a sodium ion after it loses an electron?

• Neutral

• Double positive

• Positive

• Negative

How many valence electrons does fluorine have?

• Eight

• Seven

• Two

• One

What is the chemical formula for calcium fluoride?

• CaF

• CaF2

• Ca2F

• Ca2F2

How many potassium atoms are needed to balance one oxygen atom in an ionic compound?

• Four

• Three

• Two

• One

What is the charge on an oxide ion?

• 1+

• 2-

• 1-

• 2+

What does the chemical formula of an ionic compound represent?

• The molecular structure

• The smallest charge-neutral ratio of ions

• The exact number of atoms in a molecule

• The physical state of the compound

Why is Lewis Theory more applicable to covalent compounds?

• It does not involve electron transfer.

• It only applies to non-metals.

• It is simpler to use.

• It provides insight into molecular structure.
