Definition
-group one
- one valence electron so alkali metals are very reactive |
|
|
Term
|
Definition
-group two
- two valence electrons so they are reactive but not as reactive as alkali metals |
|
|
Term
|
Definition
-groups 3-12
- not as reactive as alkali and alkaline earth metals.
- behave differently than other metals |
|
|
Term
|
Definition
- group 18
- exist as single atoms because they aren't reactive so they are therefore stable. |
|
|
Term
|
Definition
- group 17
- most reactive nonmetals because they have seven valence electrons. |
