They produce ions (negative charge)
What are Noble gases important for?
They balance an equation, they’re needed for everything.
What percentage of the periodic table are metals?
80%
What are the properties of metals?
- High thermal and electrical conductivity.
- High melting and boiling point.
- They form lattices in a solid state.
Why do they change of state?
Because of the temprature they’re in contact with.
What is a crystalline?
It’s a solid that is very pure and its internal structure is geometrical and arranged in order.
What are amorphous solids?
They hace particles in a non-arranged way and don’t havea geometrical structure.
When do we know a crystal is pure?
When it’s white.
What happens when water molecules are arranged in a symmetrical way?
