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.
se and sometimes gain electrons. Atoms with eight valence electrons do not easily lose electrons
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.

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.
se and sometimes gain electrons. Atoms with eight valence electrons do not easily lose electrons
Selenium gains two electrons to achieve a stable electron configuration, usually by forming ionic compounds in which it takes on a -2 charge.
