Ionic bonding Flashcards
What happens in ionic bonding?
Atoms lose/gain electrons to from charged particles, called ions, which are then strongly attracted to one another, due to their opposite charges. The 2 or more atoms are called a compound
Atoms with almost [ ] outer shells like to get rid of their electron(s) and become ions ( + ). Atoms with almost full outer shells like to [ ] an electron(s) and become ions ( - ). Noble gases have a [ ] outer shell

Ionic compounds all have similar properties, what are they and why? (3 and a half points)
- High melting and boiling points - due to the strong attraction between ions. It takes a lot of energy to overcome the attraction
- When they melt, the ions are free to move so they’ll carry an electric current
- They dissolve easily in water - the ions separate and are free too move in the solution (so they carry an electric current)
