Unit 1 - Group 1 Elements Flashcards
1
Q
What happens to the properties of Group 1 elements as you move down the group
A
- Increasing reactivity
- Lower boiling and melting points
- Higher relative atomic mass
2
Q
What do Group 1 elements form when they react with water?
A
They react vigorously with water to form a metal hydroxide and hydrogen gas
3
Q
What do group 1 elements form when heated in chlorine gas?
A
A metal chloride salt
4
Q
What do group 1 elements form when they react with oxygen?
A
A metal oxide
5
Q
Why does reactivity increase as you go down group 1
A
Because the outer electron is more easily lost - attraction between electron and nucleus is weaker because electron is further away from the nucleus
