2.4 Group 7 - The Halogens Flashcards
1
Q
What ions do halogens form?
A
The halogens will form ions with a 1- charge in their ionic compounds with metals
2
Q
How do the halogen form covalent compounds?
A
The halogens form covalent compounds by sharing electrons with other non-metals
3
Q
What can a more reactive halogen do to a less reactive halogen?
A
A more reactive halogen can displace a less reactive halogen from a solution of one of it salts
4
Q
What happens to the reactivity of the halogen is going down the group?
A
The reactivity of the halogens decreases going down the group
5
Q
What are the elements in group 7 called?
A
The halogens
6
Q
Why do halogens display of the halogens?
A
When a halogen is more reactive than another, it will displace the less reactive halogens ions
