CHEMICAL BONDS

 

MINERALS ARE HELD TOGETHER IN REGULAR CRYSTAL STRUCTURES BY THE CHEMICAL BONDS BETWEEN ATOMS

IONIC BONDS: ELECTRONS MOVE FROM ONE ATOM TO ANOTHER, CREATING CHARGED POSITIVE AND NEGATIVE IONS THAT ATTRACT EACH OTHER (Salt: NaCl)

COVALENT BONDS: ATOMS SHARE ELECTRONS WITH OTHERS (Carbon, Silicates)

VAN DER WALLS BONDS: WEAK BONDS BETWEEN CHAINS OR SHEETS OF ATOMS WHICH ARE HELD TOGETHER BY IONIC OR COVALENT BONDS

Quartz (SiO2)
