20.4: The Alkali Metals (Group 1) – Chemistry LibreTexts
All alkali metals react with hydrogen at high temperatures to produce the corresponding hydrides, and all reduce water to produce hydrogen gas. Alkali metal salts are prepared by reacting a metal hydroxide with an acid, followed by evaporation of the water. Both Li and Na salts are used as drying agents, compounds that are used to absorb water. Complexing agents such as crown ethers and cryptands can accommodate alkali metal ions of the appropriate size. Alkali metals can also …

Reactions of alkali metals – science-revision.co.uk
alkali metals are soft and reactive metals found in group 1 of the periodic table. They are so soft that they are easily cut with a sharp knife. Lithium is the most difficult to cut but the metals get softer as you descend the group. The alkali metals all have one electron in their outer shell and this is lost when they react to form ions with a +1 charge. As you descend the group the metals get more reactive, the reasons for this are:

Explaining reactivity – Group 1 alkali metals – BBC Bitesize
In a reaction, an atom of a Group 1 element will form an ion with a single positive charge. For example, for sodium forming a sodium ion: Na → Na+ + e- A change like this, where an electron is…

The Reactivity of Alkali Metals Explained (animation)
All the alkali metals—lithium, sodium, potassium, and so on—have only one electron in their valence shell. Because this one electron is likely to be far from the nucleus, it feels little attraction to the atom. The result: Alkali metals tend to lose this electron when they participate in reactions. These elements all look similar from the perspective of a reacting partner—the only …

21.4: The Alkali Metals, Group 1A – Chemistry LibreTexts
The alkali metals react with all group 14 elements, but the compositions and properties of the products vary significantly. For example, reaction with the heavier group 14 elements gives materials that contain polyatomic anions and three-dimensional cage structures, such as K 4 Si 4 whose structure is shown here.

Alkali Metals Reactions | Reactivity | Group IA Elements
Both potassium and sodium are alkali metals and form +1 ions. Sodium is located at third period and potassium is located at fourth period in the periodic table. So radius of potassium is higher than sodium. When radius is higher, eliminating an electron is much easy. So, potassium can eliminate its last shell electron more easily than sodium atom.

Reactions of Group 1 Elements (Alkali Metals) with Water
what happens when alkali metals (group 1 elements) react with water. You can see alkali metals react with water very fast. When going down the group, reaction rate increases and explosions can be happened due to release of large heat in a short time. do all group 1 elements react with water? Lithium, sodium, potassium, rubidium, caesium and …
