Properties of Atoms Flashcards
1
Q
What are the properties of metals?
A
- Good conductors of heat and electricity
- lustrous (shiny)
- ductile (stretchy) and malleable (hammered or pressed)
- can corrode with water
- high melting points
2
Q
What are the properties of non-metals?
A
- Poor conductors
- Dull - looking
- Not ductile or malleable (brittle)
- Exists mostly in a gaseous form
- Low melting and boiling points
3
Q
What are the properties of metalloids?
A
- Both metallic and non-metallic properties?
- Lustrous
- Usually brittle
- Semiconductors
4
Q
Metals —- and non metals —-
A
Metals lose and non metals gain
5
Q
What is group one called?
A
Alkali metals
6
Q
What are the properties of Alkali Metals?
A
- Very highly reactive
- One valence electron
- React violently with water
7
Q
What is group two called?
A
Alkali Earth Metals
8
Q
Why do elements get less reactive across a period?
A
It takes more energy to lose more electrons
9
Q
What groups are transition metals?
A
Groups 3 to 12
10
Q
What are the properties of transition metals?
A
- Some are magnetic
- Form coloured compounds
- Conductors of heat and electricity
- Form different types of compounds with non-metals
11
Q
What is group 17 called?
A
Halogens
12
Q
What are the properties or Halogens?
A
- Highly reactive non-metals
- Have seven valence electrons
- React strongly with metals
