Metal reactivity series Flashcards
1
Q
Which are the most reactive metals
A
Potassium
Sodium
Lithium
2
Q
what do we know about group 1
A
the metal gets more reactive further down the group
3
Q
why do Gp1 metals get more reactive further down the group
A
outer electrons is further from the nucleus
Attractions between nucleus and outer electron is weaker
There is shielding by full layer of shells
4
Q
how do Gp 1 metals react with water
A
they form hydrogen gas and a metal hydroxide
5
Q
what is the correlation between reactivity and losing electrons
A
The easier it is to lose an electron the more reactive the metal is
