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