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.
The Halogens Fluorine, Chlorine, Bromine, Iodine and Astatine
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.
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.
The Alkali metals (group 1) and the Alkali Earth metals (group 2) react violently with water. Lithium and magnesium show slow reactions in boiling water. Sodium and potassium reacts violently with flames with cool water. The elements in higher periods (strontium, barium etc.) react explosively.Elements in the 1st group react rapidly with cold water. The rate of reaction increases down the period. The elements in the 2nd group also reacts with hot water or steam.
all will react
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.
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.
The Halogens Fluorine, Chlorine, Bromine, Iodine and Astatine
The elements in group 1 combine easily with other elements to form compounds because they are trying to get rid of their extra electrons. That is why, for example, potassium will react strongly in water. Hope this helps.
noble gases, or inert gases they are the same thing and they are group 18 they have full valence electrons so they are unlikely to react with other elements
There are two elements in potassium chloride. One atom of potassium and one atom of chlorine react to form potassium chloride.
No, potassium is an extremely reactive metal that reacts very easily with other elements.
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.
elements are in the same group since they react similarly to other elements in that group.
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.
Potassium does not react at all with some elements such as helium, but when it reacts, it always forms a positive ion.
