Comparison the character of alkali metal and alkaline earthTO THE RIGHT (ONE PERIOD) Increases the melting

point Increasing boiling point Increased destiny Reduced atomic radius Reduced volume of the

atom Reduced base

UNDER (ONE GROUP) Increased speed Increasing atomic

radius Increased reductant Reduced boiling point Reduced melting point

HERE IS THE REACTION

REACTION: NaCl(l) → 2Na+(l) + 2Cl- (l)CATHODE : 2Na+ (l) + 2e → 2Na (l)ANODE : 2Cr (l) → Cl2(g) + 2e

Function of Alkali metals

Useful of lithiumLithium batteries used to make

Page 16: BY: ASTI RAHAYU SLAMET

Sodium cloride is used fortable salt

KNO3 used as an essential

componenet of explosive

Cont’d

For fertilizer and plant (KCl & K2SO4)use as an essential component of explosives
