alkali aka 1st group
Group 1 or alkali metals.
These metals are called alkaline earth metals.
The group I metals (Lithium, Sodium, Potassium, etc.) are very well known for their extreme reactivity. These metals will tarnish quickly in air and can cause small detonations when thrown into water via a highly exothermic reaction that produces flammable hydrogen gas.
Most non-metals are not highly reactive or an completely inert. However, the Halogens in Group 17 are reactive with nearly every substance on the planet.
Group 1 on the periodic table, known as the alkali metals, are the most reactive group of metals. They all share the chemical property of having just 1 valence electron. First ionization energies for these elements is quite low, and as you go down the group from top to bottom it gets lower. The alkali metals are so reactive that they do not exist elementally in nature; only in compounds. Sodium and potassium are the most common. Francium is the rarest.
Group 1, the Alkali Metals, which are extremely reactive.
Group 1 or alkali metals.
The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. It is difficult to say which of the two groups is more reactive. Chemists will say that Flourine is the most reactive element. Note that Group 18 is the least reactive, most stable.
They are called alkaline earth metals. They are a group of highly reactive metals.
Group 17 - the Halogens
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.
Alkali metals are found in Group 1 of the periodic table and are highly reactive, while alkaline earth metals are found in Group 2 and are less reactive than alkali metals.
Potassium is highly reactive because it belongs to Group 1 of the periodic table, which contains the alkali metals. Alkali metals are known for their high reactivity due to their tendency to lose one electron to achieve a stable electron configuration. Potassium readily reacts with water, air, and many other substances, making it a highly reactive element.
These metals are called alkaline earth metals.
The group containing the most reactive elements is Group 1, also known as the alkali metals. These elements include lithium, sodium, and potassium, which are highly reactive due to their low ionization energies and tendency to lose electrons to form positive ions.
Group 1 (alkali metals) is the most reactive group of elements. This group includes lithium, sodium, potassium, rubidium, cesium, and francium. They are highly reactive due to having only one electron in their outermost shell, which they readily donate to form stable compounds.
The first group of the periodic table contains the reactive alkali metals: lithium, sodium, potassium, rubidium, cesium, and francium.
