The Halogens Fluorine, Chlorine, Bromine, Iodine and Astatine
Alkali metals, such as sodium and potassium, are most likely to react vigorously with water. This reaction produces hydrogen gas and a strong alkaline solution.
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
Elements that do not react with other elements are typically found in the noble gases group, located in Group 18 of the periodic table. These elements have full outer electron shells, making them stable and unlikely to form chemical bonds with other elements.
A pair of elements in the same group are more likely to have similar properties. This is why groups are also called families. In the main group elements, groups 1,2, 13-18, the elements in a group have the same numbers of valence electrons in their outermost energy levels. This accounts for the fact that they behave in a similar matter in chemical reactions.
Elements from Group 17, also known as the halogens, are most likely to react with potassium to form ionic compounds. This is because halogens have a high affinity for gaining an electron to achieve a stable electron configuration and potassium has a tendency to lose one electron to achieve stability.

It is about the halogens. They are in the 17th group.

Krypton (Kr) is the Group 18 element most likely to form a compound with fluorine because it has the highest electronegativity and more tendency to react with other elements, compared to xenon (Xe) and argon (Ar).
The most reactive elements are alkali metals and halogens.
Elements from Group 17, also known as the halogens, are most likely to react with potassium to form ionic compounds. This is because halogens have a high affinity for gaining an electron to achieve a stable electron configuration and potassium has a tendency to lose one electron to achieve stability.
If you meant to say "elements ARE most likely to bond with," which is probably what you meant, then the answer would be 7A(or 17), also called the Halogens. "Halogen" actually means "salt-forming." When you take a chlorine (7A) and sodium (1A), you end up with table salt! ---- In a nutshell, the answer is Group 7A, or 17.
The noble gases.
Noble Gases, Group 8A
Francium would react most violently with hydrochloric acid but all of them would react violently. Cesium and Rubidium would certainly react explosively. Potassium would be very violent and catch fire. Sodium would be quite violent.
