Exploring Ionic and Covalent Bonds

What is the main difference between ionic and covalent bonding?

• Both ionic and covalent bonding involve transferring electrons.

• Ionic bonding involves transferring electrons, while covalent bonding involves sharing electrons.

• Both ionic and covalent bonding involve sharing electrons.

• Ionic bonding involves sharing electrons, while covalent bonding involves transferring electrons.

In ionic bonding, what happens to the electrons?

• They are shared equally between atoms.

• They are transferred from one atom to another.

• They are lost completely.

• They remain with the same atom.
