An element is a substance made from only one type of atom (e.g. oxygen is an element made up of only oxygen atoms).

An atom is the simplest form of an element that can exist, such as a lithium atom (Li).

Atoms of different elements can be combined together to create compounds, e.g sodium oxide (Na2O).

A molecule is a combination of 2 or more atoms that form chemical bonds. When these atoms are of the same element, they can be called molecules (e.g. O3 - ozone).

However when a molecule is made up of atoms of different elements, they are classified as compounds (e.g. CO2 - carbon dioxide).
So all compounds are molecules, but not all molecules are compounds.

ATOMS are the smallest substances to have unique properties. Everything, all material matter with mass, in the known universe is made up of one or multiple atoms. Each unique atom, with special properties of its own, is referred to as an ELEMENT.

A COMPOUND is 2 or more bonded atoms, even if the same element is bound to itself. These can be ionic and/or covalent bonds (amongst other types).
An example is NaCl sodium chloride, which has an ionic bond.

A MOLECULE is a substance of 2 or more atoms , however, it contains ONLY COVALENT bonds between its atoms. These can be monoatomic (only one atom) or polyatomic (many different elements.
For example, O2 or the oxygen molecule is monoatomic - 2 oxygen atoms covalently bonded.
CO2 or carbon dioxide contains a carbon double covalently bonded to 2 different oxygen atoms.

Every molecule is a compound, but not every compound is a molecule. In other words, molecule is a special subtype of compound.

to be fair, you have to have a very high iq to understand rick and morty. the humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. there's also rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from narodnaya volya literature, for instance. the fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about life. as a consequence people who dislike rick & morty truly are idiots- of course they wouldn't appreciate, for instance, the humour in rick's existential catchphrase "wubba lubba dub dub," which itself is a cryptic reference to turgenev's russian epic fathers and sons. i'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as dan harmon's genius wit unfolds itself on their television screens. what fools.. how i pity them.

and yes, by the way, i do have a rick & morty tattoo. and no, you cannot see it. it's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 iq points of my own (preferably lower) beforehand. nothin personnel kid
