Potassium is a metal, and it would react to group 17 (7A) because those elements are nonmetals.
Noble gases or group 18 elements
All of them tend not to react with each other until you get lower down the group
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).
Group-18 elements do not react. They are noble gases.They are inert in nature.Noble gases are unlikely to react. They are in the 18th period of the periodic table. They are called inert gasses too.
The noble gases, located in Group 18 of the periodic table, do not normally react chemically with other elements. They have a stable electron configuration with a full outermost energy level, making them highly unreactive.
Potassium would strongly react with the elements in group 17 and group 16.
Noble gases or group 18 elements
Group 1 elements are called alkali metals and all have a single electron in their outer shell/valence shell. These alkali metals are: Lithium (Li) Sodium (Na) Potassium (K) Rb (Rubidium) Caesium (Cs) Francium (Fr)
Lithium, sodium and potassium are all group I elements. They are also called alkali metals. They react violently with water to form strongly alkaline solutions. The elements, as we descend the group in the periodic table, become increasingly reactive.Li Na K are alkali metals. They are present in group-1. They have one valence electron.All of these elements are located in group 1 of the periodic table. Each of these elements are highly reactive metals. They react with acids to produce salts. All of these are good conductors of electricity and heat.Li,Na and K are in the 1st group of the periodic table. They are alkaline metals. They all have a valency of 1.
The most reactive non-metals are the halogens, group 17.
All of them tend not to react with each other until you get lower down the group
The elements listed are Group 1 elements, the Alkali metals. They include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr). Use the link below to check facts and learn more.
Group 16 on the Periodic Table, also known as the chalcogens, contains elements that react with oxygen to form compounds with the general formula X2O. The elements in this group include oxygen, sulfur, selenium, tellurium, and polonium.
These elements are all alkali metals. They belong to the same group (Group 1) in the periodic table, have similar chemical properties, and react vigorously with water to form alkaline solutions.
The elements of group 18 are known as inert because they havecompletelyfilled atomic orbitals.
Halogens, hands down. That would be the one second from the right that starts with Fluorine :)
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.
