the reactivity increases as you go down the group
Th reactivity of alkali metals increases from the top of Group 1A to the bottom
An example of an alkali metal is sodium (Na), which is known for its high reactivity and is commonly found in nature as part of compounds like table salt (NaCl). A non-example is magnesium (Mg), which is classified as an alkaline earth metal rather than an alkali metal, and it has different chemical properties and reactivity compared to alkali metals.
As you move down the alkali metal group on the periodic table, chemical reactivity increases. This is because the outermost electron in alkali metals is easier to lose as you go down the group, resulting in more reactive behavior with water and air. Lithium is the least reactive alkali metal, while cesium is the most reactive.
These differences doesn't exist.
The alkali metal atom with a valence shell configuration of 6s1 is francium. It is located at the bottom of the alkali metal group on the periodic table, known for its high reactivity and radioactivity.
Francium is considered the hardest metal in Group 1 (alkali metals). It is the most reactive alkali metal and is very rare in nature. Due to its high reactivity and radioactive nature, it is challenging to study and handle francium.
Reactivity increase down the group.Ceasium is the most reactive.
The outer electron configuration of an alkali metal is one electron in the s subshell. This electron is easily lost to form a cation with a full valence shell, resulting in the high reactivity of alkali metals.
Potassium is not an alkaline earth metal, it is an alkali metal. The metals in the leftmost column of the periodic table. They are noted for their high reactivity and for the fact that most of their compounds are basic.
The reactivity of alkali metals increases as you move down Group 1 from lithium to francium. This trend is due to the decreasing ionization energy, which makes it easier for the alkali metals to lose their outermost electron and become more reactive.
Potassium is a metal, characterized by its shiny appearance, high electrical conductivity, and reactivity with water to produce hydrogen gas. It belongs to the alkali metal group in the periodic table.
A fused alkali refers to a mixture of alkali metal salts that have been melted or fused together to form a homogeneous compound. This process helps to increase the solubility and reactivity of the alkali metals. These fused alkalis are often used in analytical chemistry and industrial applications.
