A
Alkali metals
2
Q
Name 2 elements in group 1?
A
Lithium Sodium Potassium Rubidium Caesium Francium
3
Q
What is the reactivity of group 1?
A
The elements get MORE reactive as you go down the periodic table
4
Q
How does Lithium react with water?
A
Fizzes, moves, released hydrogen
5
Q
How does sodium react with water?
A
Fizzed, moved around, released hydrogen
6
Q
How does potassium react with water?
A
Fizzed, moved around, released hydrogen, set fire to pink flame, popped
7
Q
How does nucleus charge affect the reactivity of group 1?
A
The higher the nucleus charge the less likely the electron will leave
8
Q
How does shell shielding affect the reactivity of group 1?
A
The more shells the less nucleus attraction
As you go down group 1 the shells increase which means the electrons get lost easier
