Group 1 - Alkali Metals Flashcards
(4 cards)
1
Q
What do alkali metals do?
A
All react with water to produce metal hydroxides
2
Q
What happens as we move down the alkali metals?
A
The atoms get bigger and their valence electrons further from the nucleus, therefore they are less attracted and more easily lost
3
Q
What happens to melting and boiling points as you go down the alkali metals?
A
They decrease
4
Q
How do difference in their reactions with air and water provide evidence for the trend in reactivity of group 1 elements?
A
The more vigorous the reaction with air or water the more reactive the metal is
