Ionic Bonding (Leaving Cert Chemistry): Flashcards

Process where atoms join together to form compounds

Substance of 2+ elements combined chemically

Atoms tend to reach $8$ electrons in outer shell when bonding

Atoms most stable with noble gas electron configuration

Transfer of electrons from one atom to another

Positively charged ion formed when atom loses electrons

Negatively charged ion formed when atom gains electrons

Lose electrons from their outer shell

Gain electrons to fill their outer shell

Attraction between oppositely charged ions

High - strong electrostatic attraction between ions

Conduct when dissolved/molten - free ions carry current

$+1$ (lose $1$ electron)

$+2$ (lose $2$ electrons)

$-1$ (gain $1$ electron)
