How many electrons will selenium lose or gain in forming an ion?
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
How many electrons does the element selenium have with the charge of negative 2?
It should gain 2 electrons
How many electrons must be gained or lost for selenium to achieve a noble gas electron configuration?
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
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.
How many valence electrons does neutral selenium have?
Neutral selenium has 6 valence electrons.
How many electrons will selenium lose or gain in forming an ion?

How many electrons does selenium gain or lose in forming an ion?
Selenium can gain 1 electron or loss 2, 4, 6 electrons.
How many electrons can selenium lose and gain?
The oxidation states of selenium are: 1 to 6 and -1, -2.
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.

It should gain 2 electrons
How many electrons selenium would arsenic lose or gain when forming an ion?
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.
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.
