well, i learnt that binary covalent normaclature(so posh) is about prefixes. Like NO(subscript 2) is called nitrogen dioxide. mono, di,tri,tetra,penta,hexa,hepta,octa,nona,deca..
Then, metal atoms are electropositive.Then tend to lose their valence electrons to other atoms to bocome cations.Noble gases are unreactive because of their complete outer shell:)
