Paper 1: Group 1 Elements Flashcards
1
Q
What are the properties of group 1 elements?
A
- soft
- reactive
- alkali
- low density
- 1 electron in outer shell
2
Q
What happens as u move down g1?
A
- The metals get more reactive as the outer electron is lost more easily due to lesser forces of attraction between the nucleus and electron
- Lower melting and boiling points
- Higher relative atomic mass
3
Q
What is the bonding between metals and non-metals?
A
Ionic bonding
4
Q
What ions do g1 elements form?
A
1+ ions
5
Q
When group metals react with H20, what do they form?
A
Hydrogen gas and Metal hydroxides (salts that dissolve in water to produce alkali solutions)
