Checkpoint 3rd Six Weeks Bonding Basics/Ionic Bonding

Explain the difference between an ionic bond and a covalent bond.

• An ionic bond involves the sharing of electrons, while a covalent bond involves the transfer of electrons.
• An ionic bond involves the transfer of electrons, while a covalent bond involves the sharing of electrons.
• An ionic bond involves the attraction between two atoms, while a covalent bond involves the repulsion between two atoms.
• An ionic bond involves the formation of a new compound, while a covalent bond involves the breakdown of a compound.

The group number in the periodic table, specifically the s and p blocks tells you what?

• Number of protons
• Number of neutrons
• Atomic mass
• Number of valence electrons

Metals tend to have what charge if it's an ion?

• postive

• negative

• neutral

Nonmetals tend to have what charge if it's an ion?

• positive "+"

• 0
• 2+
• negative "-"

How do you determine the charge for a metal if you know it's group number?

• No charge for any group
• -1 for Group 1, -2 for Group 2, and so on
• +1 for Group 1, +2 for Group 2, and so on
• +2 for Group 1, +4 for Group 2, and so on

How do you determine the charge of a nonmetal if you only know it's group number?

• group number + 8
• group number - 2
• 8 - group number

• group number + 2

What is the octet rule?

• Atoms tend to gain, lose, or share electrons in order to have a full outer shell of four electrons.
• Atoms tend to gain, lose, or share electrons in order to have a full outer shell of eight electrons.
• Atoms tend to gain, lose, or share electrons in order to have a full outer shell of ten electrons.
• Atoms tend to gain, lose, or share electrons in order to have a full outer shell of six electrons.

What two elements are the exception to the octet rule?

• oxygen and nitrogen
• hydrogen and helium
• sodium and potassium
• carbon and silicon

Define aqueous.

• A solution in which air is the solvent.
• A solution in which water is the solvent.
• A solution in which oil is the solvent.
• A solution in which fire is the solvent.

Ionic bonds are usually in what form?

• Liquid form
• Gas form
• Crystal lattice structure
• Molecular structure
