All the Group16 elements on the Periodic Table will tend to form an ion with a -2 charge. That's because all the Group 16 elements (oxygen, sulfur, selenium, tellerium and polonium are two electrons short of having a full valence shell. These atoms will try to borrow two electrons to fill their out shells, and will form -2 ions when they have been formed into ionic compounds and then dissociated into into ions.
Oxygen is the period 2 element most likely to form an ion with a charge of minus 2 because it readily gains two electrons to achieve a stable electronic configuration.
Chlorine is most likely to form the chloride ion, which has a charge of -1.
Argon doesn't form any ions as it has completely filled orbitals and is chemically inert.
Krypton (Kr) is the element in group 18 that is most likely to form a compound with fluorine. It can form compounds like KrF2 under extreme conditions.
The most likely charge on an ion formed by an element with a valence electron configuration of ns1 is +1. This is because elements with ns1 configuration tend to lose one electron to achieve a stable noble gas configuration, which results in a +1 charge.
Oxygen is the period 2 element most likely to form an ion with a charge of minus 2 because it readily gains two electrons to achieve a stable electronic configuration.
Chlorine is most likely to form the chloride ion, which has a charge of -1.
The element with a valence electron configuration of ns2 np4 is sulfur (S). Since it needs to gain 2 electrons to achieve a stable electron configuration, it is most likely to form an ion with a charge of -2.
Argon doesn't form any ions as it has completely filled orbitals and is chemically inert.
Phosphorous or nitrogen
Krypton (Kr) is the element in group 18 that is most likely to form a compound with fluorine. It can form compounds like KrF2 under extreme conditions.
The most likely charge on an ion formed by an element with a valence electron configuration of ns1 is +1. This is because elements with ns1 configuration tend to lose one electron to achieve a stable noble gas configuration, which results in a +1 charge.
The element hydrogen has a mass of approximately 1 atomic mass unit (amu) and is typically shown as having no charge in its most common form.
Potassium
Zn will most likely get a 2+ (positive) charge!
Anything in the first group on the periodic table, like hydrogen, sodium, or potassium. Though, through the strength of bonding, hydrogen is the most likely (while all the others are still very likely).
Helium is the noble gas least likely to form a compound with another element because it has a full outer electron shell, making it very stable and unreactive.
