Usually salts, from the metallic elements in group 1. However, note that hydrogen is also in group 1 and can not form salts, although it forms many other kinds of compounds.
All of them tend not to react with each other until you get lower down the group
Noble gases or group 18 elements
Group 17 elements, also known as the halogens, are the p block elements that react to form halides. They readily react with other elements to form salts called halides, such as sodium chloride (NaCl) and potassium iodide (KI).
Potassium is a metal, and it would react to group 17 (7A) because those elements are nonmetals.
The alkali metals in group 1 react by losing one electron.
Nonmetals may react with metal to form ionic compounds (salts) or other nonmetal elements to form organic compounds.
elements are in the same group since they react similarly to other elements in that group.

Noble Gases
Group 18, the noble gases, are elements that hardly react with other elements. This is because they have their full complement of eight valence electrons.
The material is most likely a nonmetal. Nonmetals are typically nonmagnetic, can be found in gaseous form, and do not conduct heat or electricity well. They often react with other elements to form compounds.
Group-18 elements least react with other elements. They are inert in nature. They are called noble gases.Elements in group 18 are less likely to react with any other elements. This group is made out of the noble gases. Its members are He, Ne, Ar, Kr, Xe and Rn.

Potassium would strongly react with the elements in group 17 and group 16.
