Ozymandias Percy Bysshe Shelly 1818
This poem is a criticism of the power of his time (Power Vs Weakness). There are three parts in the poem:
From the beggining to "the heart that fed”; I can see there a confrotation of the weakness.
From "and the pedestal...to King of Kings”; I can see a power’s reference.
From "Look on my works... to far away”; I can another weakness reference.
Shelly valorates power as a positive in term King of Kings, mighty, on the pedestal and on the other hand, he valorates the weakness as a negative in term as frown, weinkled lip, trunkless legs, colosal wreck, round the decay...

THE PARTICLES OF MATTER (PART I): ATOMS
Atoms: electrically balanced particles that consist in one positively charged centre called the nucleus surrounded by a cloud of negatively charged particles called the electrons, to exactly balance the nuclear charge.
Molecules: electrically balanced particles with more than one positive centre (nuclei). Molecules are sets of bonded atoms that act as a unit.
Ions: atoms (or groups of atoms) with unbalanced charge.
As it can be appreciated, atoms seem to be the essential particles for any kind of matter. They were thought to be the simplest possible particles, with no possibility of having parts or being broken.
