Bonding

?
What is the structure and qualities of Diamond?
4 strong covalent bonds, all electrons are used and it has a strong rigid structure.
1 of 28
What is the structure and qualities of Graphite?
3 strong covalent bonds, delocalised electrons and weak forces between layers.
2 of 28
Describe and explain properties of simple covalent compunds.
Low melting and boiling point, it doesn't take much energy to overcome the weak molecular bonds. Can't conduct electricity because there are no freely moving electrons and no charged particles.

What atoms does Ionic bonding involve?
Metals and non-metals
4 of 28
What atoms does simple covalent bonding invole?
Non-metal atoms only
5 of 28
What atoms does metallic bonding involve?
Metal atoms only
6 of 28
What structure does ionic bonding form?
Giant lattices that are brittle meanign they're easy to crush
7 of 28
What structure does simple covalent bonding form?
Molecules with weak forces of attraction so they are mainly liquids and gasses
8 of 28
What structure does metallic bonding form?
Forms a strong lattice structure

Water- needed for life
23 of 28
Give an example of a metallic bond and name a use of it.
Copper- Used for wiring electrical substances
24 of 28
How are covalent bonds formed?
It's produced when two atoms share a pair of electrons so that they can fill their ouertshell and become more stable.
25 of 28
What is a sinlge covalent bond?
When two atoms share only one pair of atoms
26 of 28
What is a double covalent bond?
When two atoms share two pairs of covalent bonds
27 of 28
Molecular substances are made up of what?
Strong covalent bonds that hold groups of atoms together
