Why do noble gases exist as single atoms?
Noble gases have a full outershell of electrons s they do not form bonds with other atoms. They exist as gases in room temperature.

Why do non-metals need to gain electrons?
To obtain full outershells and becom stable. They do this by sharing electrons eg covalent bonding
2 of 6
What is holding the atoms together?
Attraction between protons and the electrions hold everything together.
3 of 6
Why are simple molecules usually gases at room temp?
There are only weak forces holding the m klecules together (weak intermolecular forces). Heavier molecules can be in liquid or even solid form.

Give me the example of Iodine
Iodine is a grey-purple solid at room temp. When heated, only the weak intermolecular forces break to melt or boil

What is the structure of diamond?
Each carbon atoms is covalently bonded to 4 other carbon atoms in a tehtrahedral arrangement. The covalent bonds extend throughout the crytal in lattice. So each diamond is a giant single molecule.
