I have also written this question n the chemistry section nd i thought people might reply faster on this so please help.
- How group 1 metals react
- Why reactivity changes down the group
As you go down group 1 the metals are more reactive and the boiling point and melting point of the metal decreases.
Lithium is the least reactive, it floats and fizzes
Sodium is the second least reactive - melts, skates on water and sparks on yellow flame
Potassium is the third most reactive - violoently whizzes on water and catches on fire
THANKYOU SOOOOO MUCH
:D :D :D
UR welcome :)
do you need to know anything else ?
what is the word and balanced symbol equation for sodium reacting with water.
Na + H2O --> NaOH + H2
2Na + 2H2O --> 2NaOH + H2
hats great thanks
its okay :) .. do u need anyfine else or u okay ?
Reactivity changes as you go down the group because the electron shells are progressively further from the nucleus, and are therefore less tightly bound to it. Less tightly bound = more reactive.
