Exploring Ionic and Covalent Bonding Concepts

What is the main difference between ionic and covalent bonding?

• Ionic bonds involve transferring electrons, while covalent bonds involve sharing electrons.

• Ionic bonds involve sharing electrons, while covalent bonds involve transferring electrons.

• Ionic bonds occur between non-metals, while covalent bonds occur between metals.

• Ionic bonds are weaker than covalent bonds.

In an ionic bond, what happens to the electrons?

• They are shared equally between atoms.

• They are shared unequally between atoms.

• They are transferred from one atom to another.

• They remain with the same atom.

What type of charge does a sodium ion acquire after losing an electron?

• Double negative

• Neutral

• Negative

• Positive

What is the force that holds ions together in an ionic bond?

• Electrostatic force

• Magnetic force

• Nuclear force

• Gravitational force

In a covalent bond, how are electrons distributed between atoms?

• They are transferred from one atom to another.

• They are shared between atoms.

• They are lost to the environment.

• They are absorbed by the nucleus.
