What are some properties/features of alkali metals?
Silvery solids,stored in oil,handled with forceps/burn skin,and have LOW DENSITY,ONE outer electron
1 of 5
What are the trends in group 1?
As you down GROUP 1 they become MORE REACTIVE because the OUTER ELECTRON is more easily LOST as it's FURTHER from the nucleus,also DOWN=LOWER melting/boiling points
2 of 5
What are some of the alkali metals in group 1?
*Lithium,Sodium,Potassium(+rubidium,caesium)
3 of 5
What do alkali metals form with non-metals?
IONIC COMPOUNDS;want to LOSE their ONE outer electron to have 1+ ion,ALWAYSSSSS form ionic bonds-white compounds which dissolve in water>>>colourless solutions
4 of 5
When alkali metals react with water what happens;products,reaction,testing etc?
*produces HYDROGEN GAS *Lithium,sodium,potassium>>water=VIGOROUS(float,move,FIZZ) Lighted splint=hydrogen test(squeaky pop as H2 ignites)*Form HYDROXIDES,dissolve in water =alkaline solutions
