3.1 Ionic Bonds

Metals bend easily without breaking, while crystals are brittle

Metals have many bright colors, just like crystals

Gems always feel warmer to touch than metals

Gems are magnetic, but metals aren't

Often gases or non-conductive solids

atoms can shift slightly and bend

specific lattice

Atoms achieve eight valence electrons to become stable

Atoms always fill all energy levels completely

Atoms must have paired electrons in every subshell

Atoms prefer seven valence electrons for bonding

Eight valence electrons

Six valence electrons

Ten valence electrons

Two valence electrons

+2 charge cations

+1 charge cations

−1 charge anions

−2 charge anions

lost two valence electrons

gained two valence electrons

Shares two core electrons

gained one valence electron

Eight valence electrons in outer shell

Two electrons in 3s and six in 3p

Complete octet, unstable electron configuration

Electron dot shows only valence

Argon electron configuration

Neon electron configuration

Helium electron configuration

Krypton electron configuration

Cations form from losing electrons; anions form from gaining electrons

Anions form from losing electrons; cations form from gaining electrons

Both gain electrons to reach octet

Both lose electrons to reach octet
