Selenium gains two electrons to achieve a stable electron configuration, usually by forming ionic compounds in which it takes on a -2 charge.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
It should gain 2 electrons
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
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.
Neutral selenium has 6 valence electrons.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
Selenium can gain 1 electron or loss 2, 4, 6 electrons.
The oxidation states of selenium are: 1 to 6 and -1, -2.
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.
It should gain 2 electrons
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.
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 has 34 electrons.
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
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 symbol for a selenium atom gaining two electrons is Se2-.
Neutral selenium has 6 valence electrons.
