F (fluorine) will form an anion.
The element most likely to form an anion is Cl (chlorine). This is because chlorine has a high electronegativity and tends to gain an electron to achieve a stable electron configuration, forming the chloride ion (Cl-).
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.
Potassium
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.
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).
The element most likely to form an anion is Cl (chlorine). This is because chlorine has a high electronegativity and tends to gain an electron to achieve a stable electron configuration, forming the chloride ion (Cl-).
Nitride N^3- Phosphide P^3- Phosphate PO4^3-
An anion is named using the base element with an -ide suffix. Ex: Br- (Bromine anion) is named bromide sulfur- sulfide, ect.
An element such as sodium, which readily gives up an electron to achieve a stable electron configuration, would likely form an ionic compound with fluorine. Sodium would form a sodium cation (Na+) and fluorine would form a fluoride anion (F-), creating an ionic bond between the two elements.
The element E is likely barium (Ba), as its electron configuration is Kr 5s2. The fluoride compound of barium would be BaF2, with barium losing its two valence electrons to form a 2+ cation and fluoride gaining one electron to form a 1- anion.
Phosphorous or nitrogen
Potassium will most likely form a cation with a +1 charge.
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.
as we know that in the modern periodic table most electronegative element is fluorine which forms anions basically therefore the answer is opposite elements with low electronegative form anion usually
Chlorine is the most common anion in the body. Chlorine is an element that is utilized in industry, as well as found in common household products.
Potassium
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.
