Alkali metals are lithium, sodium, potassium, rubidium, caesium and francium.
They are the metals with the higher chemical reactivity.
1 answer
Alkali metals are the elements in the first column of the periodic table, also known as Group 1. This group includes elements such as lithium, sodium, and potassium. Alkali metals are highly reactive and exhibit similar chemical properties due to their single outer electron configuration.

I give an example for ammonium salt ....hmm.... lets just take ammonium chloride as an example . How about alkali ? I take calcium hydroxide as an example for alkali . Calcium hydroxide is formed when calcium oxide reacts with water whereas ammonium chloride is formed when hydrochloric acid reacts with ammonia solution . Calcium hydroxide (alkali) + ammonium chloride (ammonium salt) --> calcium chloride + carbon dioxide + water .

Alkali metal hydroxides are strong bases that are highly water-soluble, forming alkaline solutions. Alkaline earth metal hydroxides are also bases but are less soluble in water compared to alkali metal hydroxides, resulting in less alkaline solutions.

One of the alkali metals used in fireworks is potassium. It is commonly used to produce a lilac or light purple color in fireworks displays. Potassium salts are often incorporated into the compositions of fireworks to achieve colorful effects.

False. Alkali metals lose one electron to form a stable electron configuration with a full outer shell of electrons, which is the stable electron configuration for these elements.

Alkali metals, such as lithium, sodium, and potassium, are highly reactive and can react violently with water or air. This can pose safety hazards and make them unsuitable for use in voltaic cells where stability and controlled reactions are required. Instead, non-reactive metals like zinc and copper are commonly used in voltaic cells.

Sodium (Na) is the alkali metal in period 3 of the periodic table. It is located in group 1 and is known for its high reactivity with water and air. Sodium is commonly found in salts, such as sodium chloride (table salt).

Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy
Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy

Alkali metals are extremely reactive and therefore are never found in their metallic state - only in compounds. As an example sodium metal is never found in nature only as compounds like salt etc.

Alkali metal is a term that refers to six elements: lithium, sodium, potassium, rubidium, cesium, and francium.
These elements make up group I of the periodic table of elements.
They all form singly-charged positive ions, and are extremely reactive.
They react violently with water, forming hydroxides and releasing hydrogen gas and heat.
Cesium and francium are the most reactive and lithium is the least.

Alkaline-earth metals do react with oxygen, forming oxides. The reaction tends to be less vigorous compared to alkali metals, as alkaline-earth metals have a higher ionization energy. Examples of alkaline-earth metal oxides include magnesium oxide (MgO) and calcium oxide (CaO).
