Please help.
1)Particulate model of matter and Kinetic
particle theory? What’s the difference between
them?
2)Do all compounds exist as
molecules?
Thank you.
1) No difference, as far as 'O' levels or 'A' levels are
concerned.
2) No. Molecules imply only covalent bonding present (eg. H2O).
Some compounds are ionic in terms of their bonding. (eg. Na+
Cl-).
