Periodic table Flashcards
1
Q
Alkali Metals properties
A
- Low m.p and b.p
- Low density
- Very soft
2
Q
Alkali Metals Reactivity
A
- Very reactive
- 1 electron in outer shell
- More reactive down group
- Electron to lose further from Nucleus
3
Q
Alkali Metals Reactions
A
- React with water to form metal hydroxide + Hydrogen
- React with oxygen to form metal oxide
- Reactions with water and oxygen are very vigorous
4
Q
Halogens properties
A
- Low m.p and b.p
- Poor conductors
5
Q
Halogens reactivity
A
- Very reactive
- 7 electrons in outer shell
- React by gaining electron
- Less reactive down group
- Attraction for new electron is further from Nucleus
6
Q
Halogens Reactions
A
- Very vigorous reactions with Hydrogen
- Form ions with 1- charge
- More reactive replace less reactive Halogens in displacement reactions
7
Q
Transition Metal properties
A
- Good conductors
- Hard and strong
- High density
- High m.p and b.p
8
Q
Transition Metal reactivity
A
- Very Unreactive
- Can form multiple different Ions (v important)
9
Q
Transtion Metal reactions
A
- Almost never react
- Sometimes react v slowly with water or oxygen e.g rusting
- React to make coloured compounds
10

- Daltons table of elements
- Newlands table of octaves
- Medeleevs periodic table
