Covalent Bonding Flashcards
Covalent bond
A shared pair of electrons, 2 non metals bonding together
Period number
Number of electron shells
Simple covalent molecules state at room temperature and why
They are liquid orgas at room temperature because they have low melting and boiling pints
Why do simple covalent compounds have low melting and boiling points
Because they have weak intermolecular forces which require little energy to break
Simple covalent bonding examples
Water, methane, oxygen, carbon dioxide, chlorine
Why do simple covalent molecules not conduct electricity
Because there is no overall charge
What are polymers
They are very large molecules made when hundreds of monomers join together to form long chains
Plastics are..
They are synthetic polymers that can be shaped by heat or pressure.
What state is plastic at room temperature and why
Solid at room temperature because have high melting and boiling points
Simple molecules are
Small molecules that have strong covalent bonding with weak intermolecular forces of attraction between small molecules
