An ION is an atom that has an overall charge because it has lost or gained electrons.
1 of 20
When are IONIC BONDS formed?
When ions that have opposite charges attract.
2 of 20
What is an IONIC BOND?
The ELECTROSTATIC ATTRACTION of positive and negative ions.
3 of 20
What are the states of matter?
Solid, Liquid and Gas
4 of 20
By which process do you take something and turn it into a liquid from a solid?
By melting
5 of 20
What is BOILING?
Turning something from a liquid into a gas
6 of 20
What is CONDENSING?
Turning something from a gas into a liquid.
7 of 20
What is FREEZING?
Turning something from a liquid into a solid
8 of 20
Which kinds of metals form IONIC BONDS?
Metals and non-metals
9 of 20
All ionic compounds have these properties:
-Strong electrostatic forces of attraction
-High melting and boiling points
-When molten or dissolved it can conduct electricity
-Giant ionic crystal/lattice structure.
10 of 20
What state are ionic compounds at room temperature?
Solid
11 of 20
Why can ionic compounds not conduct electricity when they are solids?
Because the ions are packed together and can not move.
12 of 20
Why can ionic compounds carry an electric current?
Because they are charged particles.
13 of 20
What happens when ionic compounds are molten?
The lattice breaks up and the ions are free to move.
14 of 20
What are allotropes?
Are forms of an element that exist in the same state, but have different properties because their atoms are arranged differently.
15 of 20
Are diamonds hard or soft?
They are very hard because the carbon atoms have a giant, ridged covalent structure.
16 of 20
Do diamonds have a high or low melting point?
They have a very high melting point because all of the carbon atoms are joined together by very strong covalent bonds
17 of 20
Can diamonds conduct electricity or heat?
No because the electrons are fixed and there aren't any free electrons to flow the electricity.
18 of 20
What are the properties of metals?
-ductile
-malleable
-high melting/boiling points
-sonorous
-shiny
-crystalline
-usually hard
