Covalent Bonding Flashcards
Describe a covalent bond:
electrostatic attraction between a shared pair of electrons in order to gain a full outer shell of electrons
What is a double bond?
2 covalent bonds between the same atoms, 4 electrons are being shared
How can you draw a covalent bond?
dot and cross diagram
Covalent bonds are between…
non-metal atom and a non-metal
What forms a covalent bond?
sharing of 2 electrons
Explain the force between molecules:
there are weak intermolecular forces between the molecules so do not take much energy
Simple molecules have low melting and boiling points
Why cannot simple molecules not conduct electricity?
no overall charge so cannot carry charge in order to conduct electricity
Why do larger covalent bonds require more energy to overcome the bonds?
the larger the covalent bond, the intermolecular forces increase so more energy is require to break the bonds
