1

what are the two general forms of solids and what makes them different?

crystalline: regular and orderly array

amorphus: disordered network of strongly bonded atoms

2

what are the different types of solids and what makes them different?

atomic: consists of invididual atoms packed in a regular crystalline array with relatively weak dispersion forces between the atoms. only the noble gases form atomic solids at low temp

metallic: atomis with a low ist ionisation energy form similar array as atomic, valence electrons form a delocalised cloud of electrons

ionic: formed by ions

molecular: molecules held together by intermolecular forces

network covalent: atoms linked by strong covalent bonds in an extensive 3 dimensional network through the whole solid

3

what are some properties of solids?

fixed shape
high density
low compressibility

4

what are some properties of liquids?

-kinetic energy of molecules is comparable to intermoleculer forces
-able to flow
-no fixed shape, high density, has a surface and surface tension
-viscosity that can be explained by intermoleculer forces

5

what is viscosity?

the measure of a liquids resistance to flow

6

what is surface tension?

the resistance of a liquid to increase its surface area
