Covalent Bonding Flashcards
Covalent bonding is formed by…
Sharing a pair of electrons between two atoms
There are … Forces between the bonding pair of electrons and the (positive) nuclei of the atoms involved
Strong electrostatic
The reactants are…
Non metals
The term … Goes with covalent bonding
Molecule
Simple Molecular Structures are…
Gases, liquids or solids
Simple Molecular Structure have … Melting points
Low
The covalent bonds between the atoms in a molecule are …
Strong
The forces of attraction between molecules in a simple molecular structure are…
Weak
They are … In water and … In organic solvents
Insoluble in water and soluble in organic solvents
Simple molecular structures … Conduct electricity
Do not conduct electricity as the molecules have no overall charge and there are no electrons mobile enough to move from molecule to molecule
Giant covalent structures have … Charged ions
No charged ions
All the atoms in a giant covalent structure are … By … And packed into …
Are joined up to their adjacent atom by extremely strong covalent bonds and packed into giant regular lattices
Giant covalent structures have … Melting points
Very high melting points as a lot of energy is needed to provide the energy to break apart the many strong covalent bonds
Giant covalent structure are … In water
Insoluble in water
