K potassium reacts readily with Cl chlorine because the electron configuration changes to that of a noble gas. Group 7a would be the best guess.
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.
Potassium is more reactive than sodium. This is because potassium is lower in the alkali metal group and has one more electron, making it more likely to lose that electron and react with other elements.
Mg will most likely react with elements in Group 17 (halogens) to form ionic compounds, such as magnesium chloride (MgCl2).
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.
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.
Potassium would strongly react with the elements in group 17 and group 16.
Potassium is a metal, and it would react to group 17 (7A) because those elements are nonmetals.
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.
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.
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 more reactive than sodium. This is because potassium is lower in the alkali metal group and has one more electron, making it more likely to lose that electron and react with other elements.

This accounts for the fact that they behave in a similar matter in chemical reactions.
Elements in the same group as potassium, such as sodium and lithium, would react similarly due to their similar outer electron configurations. These elements are all alkali metals and exhibit similar reactivity characteristics, such as forming ionic compounds easily and reacting violently with water.
Potassium bromide can react with elements like chlorine to form potassium chloride and bromine. It can also react with sulfur to form potassium sulfide and bromine. Additionally, it can react with metals like magnesium to form magnesium bromide and potassium.
The group likely to react with chlorine to form XCl is the alkali metals group, such as sodium, potassium, or lithium. Alkali metals readily form ionic compounds with chlorine by donating an electron to chlorine, resulting in the formation of XCl.
