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 will nitrogen gain from forming an ion?
Three. In fact, any element in the same column of the periodic table as nitrogen will also gain three electrons when forming an ion.
How many electrons will strontium gain or lose in forming an ion?
It will lose 2 to form Sr2+
How many electrons does O need to achieve noble gas?
Oxygen should gain 2 electrons to achieve noble gas configuration
How many electrons will chlorine gain from forming an ion?
Chlorine will gain one electron when forming an ion. Chlorine therefore fills its valence electron shell with 8 e-. Chlorine usually bonds with group 1 metals, like Na (Sodium).
How many electrons will sulfur gain from forming an ion?
2 like oxygen
How many electrons selenium would arsenic lose or gain when forming an ion?
Selenium will gain two electrons and arsenic will gain three electrons
How many electrons will phosphorus gain or lose in forming an ion?
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
How many electrons will bromine gain from forming an ion?
1
How many electrons that an atom in the oxygen family gain or share?
Atoms in the oxygen family can gain or share two electrons in order to achieve an octet of electrons.
How many electrons will oxygen gain or lose when forming an ion?
Under the usual chemical conditions oxygen gains 2 electrons to form ions. However when ionized by electrical discharges or other high energy physical processes oxygen can lose any number of electrons to form ions (even all of its electrons).
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 will Calcium gain in forming an ion?
None.Calcium loses 2 electrons to form 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 will nitrogen gain from forming an ion?
Three. In fact, any element in the same column of the periodic table as nitrogen will also gain three electrons when forming an ion.
When forming an ion bromine is most likely to gain how many electrons?
Bromine will gain one electron.
How many valence electrons does oxygen gain?
Oxygen tends to gain two electrons to complete its "octet", making it O2- with the electron configuration 1s22s22p6
