Helium does not form ion.
This is the electrical charge of the ion.
All the elements in Group 2A (Mg, Ca, etc.). A charge of 2+ is acquired by these metals in order for a more stable state to be achieved.
Neon does not form any compounds or ions.
The answer is Ni3+
net negative charge
ionic bond
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
All the listed elements form ions with a charge of 1, if "1" is taken as the absolute value of the charge on the ion. For fluorine, however, the corresponding ion has a charge of -1.
By charge transfer.
sodium
It would form the negatively charged phosphide ion with a charge of 3-, and the symbol P3- .
Helium does not form ion.
sodium
The phosphide ion, meaning phosphorous by itself not bound up in a poly-atomic ion, has a charge of -3 in ionic compounds.
Not int its elemental form but it does form the nitride ion, which carries a -3 charge.
Potassium is a group 1 element, so it will form a 1+ ion.
