How can the arrangement of elements in the Periodic Table be used to predict how they react with other elements to form compounds?

u really shouldn't be using this to complete ur homework but . . .
elements on the periodic table r arranged so that elements with like properties r together, such as the noble gases and others. if u basically know how 1 element reacts with another element, then u can take a reasonable guess that an element of the same family will work similiarly with the other element, tho it's not guaranteed.

the ones on the extreme right have full outer shells, so are inert
The ones just left of them need an extra electron to fill its outer shell
The ones on the extreme left have an electron by itself on the outer shell and is looking to use that to fill another element's shell
eg Hydrogen is extreme left, Oxygen is 2 in from the right
So H has extra electron, O needs 2 electrons to fill its outer shell
2 of those H will stablize the O
ever heard of H2O = water
