Ionic Bonding Flashcards
What is the primary characteristic of ionic bonding?
Ionic bonding involves the transfer of electrons from one atom to another.
True or False: Covalent bonds form between metals and non-metals.
False: Covalent bonds typically form between non-metals.
What type of structure do ionic compounds form?
