Worksheet time: 6mins
When atoms share electrons so that they both get a full outer shell.
Covalent bond
Ionic bond
Compound
Pairing
Weak attractive forces between molecules. When a simple covalent substance melts or boils, it is these forces that are broken (not the covalent bonds in each molecule).
Covalent forces
Electronic forces
Intermolecular forces
Intermolecular bonds
The "properties" of a material are...
...its characteristics, features, and behaviour.
...what the material owns.
...only what it looks like.
...only how it behaves in certain situations.
A substance's ability to allow heat or electricity to pass through it
Charge
Conductivity
Reactivity
Liquidity
Usually electrons or ions, which move through a substance as electricity.
Chargers
Charged particles
Electroballs
Electric carriers
Electrons that are not attached to a particular atom.
E.g. in a metal, outer electrons can be free to move through the solid.
Loose
Independent
Delocalised
Disconnected
If two atoms are 'attracted' to each other, it means they....
...really like each other
...both feel a force pulling them together
...are touching each other
...cannot be separated
When electrons are lost by one atom and gained by another, so that they both get full outer shells.
Covalent bond
Ionic bond
Pairing
Compound
What is an 'ion'?
A particle found in the nucleus of an atom
Something in the periodic table
A tool you use for flattening clothes
An atom that has lost or gained electrons
A type of covalent bond where four electrons (two pairs) are shared between two atoms.
Pair bond
4-way bond
Secondary bond
Double bond
