electrostatic
3
Q
what forces hold covalent bonds together?
A
electrostatic
4
Q
which electrons do covalent bonds share?
A
electrons in the outer shell
5
Q
properties of giant covalent structures
A
very high melting and boiling points and don’t conduct electricity (apart from graphite and graphene)
6
Q
what do substances containing covalent bonds usually have?
A
simple molecular structures
7
Q
characteristics of simple molecular structures
A
low melting and boiling points (due to weak intermolecular forces), usually gas or liquid at room temp
