Q
grp 1
A
alkali metals
2
Q
grp 1 properties
A
- highly reactive
- soft metals
- low density
- low mp, bp
- react w/ halogens to form halides
- react w/ water to form metal hydroxide + h2
- react w/ oxygen to form metal oxide
3
Q
grp 2
A
alkaline earth metals
4
Q
grp 2 properties
A
- higher mp bp than grp 1 (decrease down the group)
- harder and denser than grp 1 (increases down the group)
- less reactive than grp 1 (increases down the grp)
5
Q
grp 1 & 2 trends
A
- mp bp decreases down the group
- density increases down the group
- reactivity increases down the grp
6
Q
group 7/17
A
halogens
7
Q
grp 7/17 properties
A
- highly reactive nonmetals
- exist as diatomic molecules
- low mp bp
8
Q
group 7/17 trends
A
- reactivity decreases down the group
- mp bp increase down the group
- color darker down the group
9
Q
group 0/8/18
A
noble gases
10
Q
noble gas properties
A
- low mp bp
- very unreactive (inert gases)
- colorless, oderless, tasteless
- exist as monoatomic gases
- dont form compound easily
- used in lighting (ex. neon)
11
Q
noble gas trends
A
- density increases down the group
- mp bp incerases down the group
12
Q
transition metal
A
- used as catalyst
- multiple oxidation states
- less reactive
