covalent bonding

define covalent bond

when two non metal atoms share electrons

define simple molecule

covalent bonds within each molecule

how does electrostatic force take place in simple molecule

when the positive nuclei is attracted by the negative electrons.

properties of simple molecule

low melting and boiling point

don’t conduct electricity

insoluble of water

how has electrostatic force taken place in giant covalent

nuclei and shared electrons are attracted.

what are the two main structure in giant covalent

diamond

graphite

what is the properties of diamond

each carbon atoms are connected to 4 others

high melting point

very hard

doesnt conduct electricity

properties of graphite

layers of carbon atoms in hexagon rings (weak forces between each layer making them soft)

high melting point

can conduct electricity
