An alkali metal is any Group 1 metallic elements: lithium, sodium, potassium, rubidium, cesium and francium; all are strongly reative, soft low density metals. Which means if they come in contact with a halogen it can cause a vigorous reaction.
Yes
The reactivity of metals with water often follows a general trend based on their position in the periodic table. Alkali metals, such as sodium and potassium, react vigorously with water, producing hydrogen gas and a hydroxide. Alkaline earth metals, like calcium, react less vigorously, while transition metals typically show little to no reaction with water. Thus, the pattern indicates that reactivity decreases from alkali metals to transition metals.
Alkali metals, such as sodium (Na) and potassium (K), react vigorously with water to produce hydrogen gas. When these metals come into contact with water, they undergo a rapid oxidation reaction, releasing hydrogen gas and forming hydroxides. This reaction can be explosive, especially with heavier alkali metals.
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
Highly reactive metals that easily combine with other elements are called alkali metals, like sodium and potassium. They react vigorously with water and oxygen.
Yes
All alkali metals and alkali earth metals below calcium react vigorously with acids.
Alkali Earth metals are the most reactive metals on the periodic table.
Alkali metals react vigorously with water, producing hydrogen gas and forming alkaline solutions. They react with oxygen to form oxides, and with noble gases they can form compounds under certain conditions, although the reactivity is not as intense as with water or oxygen.
They do react vigorously.
Transition metals such as copper, silver, and gold are less reactive than alkali metals and alkaline-earth metals. These metals are less likely to react vigorously with water or air compared to alkali and alkaline-earth metals.
Alkali metals are all of the elements on the far left hand side of the Periodic Table with the exception of hydrogen. They are all highly reactive metals that also react vigorously with water.

Many. All the alkali metals will react explosively with it. All the alkaline earths will also react extremely vigorously. Group 3 metals from Al and below will and many transition metals do also. Copper, silver and Gold do not.
They don't
Alkali metals, such as sodium (Na) and potassium (K), react vigorously with water to produce hydrogen gas. When these metals come into contact with water, they undergo a rapid oxidation reaction, releasing hydrogen gas and forming hydroxides. This reaction can be explosive, especially with heavier alkali metals.
alkali metals react violently in cold water
