In order to form an octet an atom of selenium will lose or gain?

An atom of selenium will gain two electrons to achieve an octet because it has six valence electrons in its outer shell. By gaining these two electrons, selenium will have a total of eight electrons in its outer shell, fulfilling the octet rule.


How many electrons does selenium need to lose or gain to be stable?

Selenium needs to gain two electrons to achieve a stable electron configuration. By gaining two electrons, selenium will have a complete outer energy level (valence shell), which is the most stable configuration for an atom.


Does selenium need to gain 2 electrons to for an octet?

Yes, selenium needs to gain 2 electrons to achieve an octet configuration because it has 6 valence electrons in its outer shell. By gaining 2 more electrons, selenium can reach a stable electron configuration with 8 electrons in its outermost shell.
