Why are compounds formed?

• Compounds are higher energy (less stable) than the individual atoms

• Compounds are lower energy (more stable) than the individual atoms

• No one knows why compounds would form

What are valence electrons?

• Total number of electrons in the atom

• Outermost electrons

• Electrons that have been gained or lost by the atom

What is the main difference between ionic and covalent bonding?

• Ionic bonding involves the sharing of electrons, while covalent bonding involves the transfer of electrons.

• Ionic bonding involves the transfer of electrons, while covalent bonding involves the sharing of electrons.

• Both ionic and covalent bonding involve the sharing of electrons.

• Both ionic and covalent bonding involve the transfer of electrons.
