Sodium, Potassium, and the rest vertically below it on Periodic Table.
The boron family is moderately reactive. Boron itself is a relatively unreactive element, while the elements below it in the group, such as aluminum, can be more reactive due to their ability to form stable compounds with other elements.
The most reactive non-metals are the halogens, group 17.
Noble gases, such as helium, neon, and argon, are the least chemically reactive elements. They have a full outer shell of electrons, making them extremely stable and unlikely to form chemical bonds with other elements.
The most reactive non-metals are the halogens, group 17.
Argon belongs to group VIII, the noble gas family. Elements in group VIII are the most uncreative elements, thus it is safe to store reactive substances in them because they will not react with the reactive substance.
The most reactive nonmetal is fluorine
halogenes
The noble gases are the least reactive among all chemical elements.
The boron family is moderately reactive. Boron itself is a relatively unreactive element, while the elements below it in the group, such as aluminum, can be more reactive due to their ability to form stable compounds with other elements.
alkali metals
halogen
halogen
S block has the most reactive elements. The groups 1 and 2 belongs to the s block.
Noble gases, also known as Group 18 elements, are generally the most non-reactive family of elements on the periodic table. They have a full outer electron shell, making them stable and unlikely to form chemical bonds with other elements.
Noble gases are the most un-reactive family of elements. They have a full valence electron shell, making them stable and unlikely to form chemical bonds with other elements.
Alkali metals in the first group compose the most reactive family of metals.
The most reactive non-metals are the halogens, group 17.
