Ionic Bonding (OCR GCSE Chemistry A (Gateway Science Suite)): Flashcards

Atom/group of atoms with positive or negative charge

To achieve full outer shell of electrons (more stable)

Lose electrons from outer shell

Positively charged ions

Metal atoms

Na loses 1 electron to form $ext{Na}^+$

Gain electrons to fill outer shell

Negatively charged ions

Non-metal atoms

O gains 2 electrons to form $ext{O}^{2-}$

One atom transfers electrons to another atom

Metal and non-metal

Electrostatic forces

Giant ionic lattice

High (strong forces between ions)
