None! Elements such as Kr are noble gases He, Ne, Ar, Kr, Xe, Rn, and they do not form ions.
To determine the likely ion formed by an element like Kr (krypton), you need to consider its position on the Periodic Table. Kr is a noble gas located in the far right column, meaning it has a full valence electron shell and is stable. Noble gases do not readily gain or lose electrons, so Kr is unlikely to form an ion.
carbon is formed
You didn't provide an ion. So since it's a positive most likely a negative ion.
N and P for example. Nitrogen will form a N3- the nitride ion.
An ion.
Arsenic will form a -3 Anion.
negative ion
No clue, mate.
Metals and nonmetals form ionic bonds. The metal becomes a positively charged ion, and the nonmetal becomes a negatively charged ion.

which valance shell electron configuration of neutral atoms would represent an element most likely to form a 2-ion?
Argon doesn't form any ions as it has completely filled orbitals and is chemically inert.

sodium
Compound known as chloride contain the element chlorine, typically in the form of the chloride ion.
Potassium is a group 1 element, so it will form a 1+ ion.
