The symbol is Se(2-).
Selenium can gain 1 electron or loss 2, 4, 6 electrons.
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.
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.
Selenium typically gains two electrons to achieve a stable electron configuration, forming the Se2- ion. Arsenic typically loses three electrons to achieve a Noble Gas electron configuration and forms the As3+ ion.
Atoms that join by a covalent bond share electrons but do not gain or lose them. In a covalent bond, the electrons are shared between the atoms, creating a stable electron configuration for both atoms involved.

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.
The oxidation states of selenium are: 1 to 6 and -1, -2.
Selenium typically gains two electrons to achieve a stable electron configuration, forming the Se2- ion. Arsenic typically loses three electrons to achieve a Noble Gas electron configuration and forms the As3+ ion.
It should gain 2 electrons
When atoms lose or gain electrons, they form ions. These are charged particles.
Selenium gains two electrons to achieve a stable electron configuration, usually by forming ionic compounds in which it takes on a -2 charge.
