Alkali metals are the elements in the 1st group. In the 1st group,the reactivity of the elements increase down the group. Cs is the most reactive alkali metal.
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
The most reactive non-metals are the halogens, group 17.
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
An alkali metal is a group of chemical elements in the first column of the periodic table, including lithium, sodium, potassium, rubidium, cesium, and francium. These metals are highly reactive, soft, and have low melting points. They are known for their ability to quickly form alkaline solutions when they react with water.
Non-reactive elements in the periodic table are typically the noble gases, such as helium, neon, and argon. These elements have a full outer electron shell, making them stable and less likely to form chemical bonds. Reactive elements are those that readily form chemical bonds with other elements, such as the alkali metals (e.g. sodium, potassium) and halogens (e.g. fluorine, chlorine).
Alkali metals are group-1 elements. They are located at extreme left in periodic table.
Group 1 (for metals) and group 17 (for non metals).
The alkali metals are a series of chemical elements. They are part of group 1. Lithium (Li) Sodium (Na) Potassium (K) Rubidium (Rb) Caesium (Cs) Francium (Fr)
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
The most reactive non-metals are the halogens, group 17.
Elements in group 1 (alkali metals) are typically more reactive with oxygen compared to group 11 (coinage metals). This is because alkali metals have a lower ionization energy and are more likely to form ionic compounds with oxygen.
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
The most reactive metals are the alkali metals in group 1a.
Group 1 (metals) and Group 17 (non-metals).
Alkali metals in the first group compose the most reactive family of metals.
These elements are francium and lithium.
The halogens (group 9) and the earth metals (group 1)
