Do all atoms want to completely fill up their shells with electrons?

or do the y want to becom nuetral and have has many electrons has they have protons?

Do all atoms want to completely fill up their shells with electrons?
They want to completely fill up their recent shells with electrons that the geting or giving of electrons based on atom's recent shell. some atoms want to give his electrons from their recent shells, some atoms want to get any electron. if electrons is less in recent shell, the atom gives, so they became more stable.
Reply:They need a full outer shell to react. otherwise they won't react.
Reply:All atoms want to complete their shells since this configuration is very stable and its similar to that of noble gas which are inert chemically. They have no trend to prefer neutrality
Reply:atoms love becoming ions (full outer shell) so take magnesium for example, that has 2 electrons in its outer shell so 2 is closer to 0 so it likes to donate electrons whereas oxygen has 6 electrons in its outer shell so it wants to receive electrons to fill its outer shell to 8. generally, any outer shell from 1-3 will donate and from 5-7 will accept electrons, 4 (eg, carbon) can go either way and inert/noble gases such as neon and argon already have a full outer shell so are not reactive.
Reply:They technically want both.



They want their shells filled with (usually) eight electrons each. If they have less than 4 in the outer shell, they prefer to lose them; if they have more, they prefer to gain them (if they have exactly 4, it can go either way).



Once they do have a full shell, however, they've got charge, and they need to hook up with something else with ti.
Reply:They want to fill their shells apart from the inert gases (Group VIII) who are sorted already.
Reply:I beleive your talking about the Octet rule.



Its not a question of "Wanting" but rather of stability, atoms with their outermost shell full of electrons are more chemically stable (in general) than their electrically neutral selves. This is party why atoms come together the way they do to form more complex structures.
Reply:Yes but sometimes they share electrons this is called a covalent bond, all molecules are trying to gobble up as many electrons as possible.
Reply:they basically want to have a full outer shell, in whichever way possible.
