The group you're thinking of is group 1, the alkali metals. They include sodium and potassium, and you're right, they are so reactive that they do not exist by themselves. They only exist in compounds with other elements.
group 1 and 2
They are named as Group(I) in the Periodic Table. However, they are also known as the Alkali Metals. They are Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium. Francium is never found in the open lab, as it is radio-active.
Sodium is highly reactive and never exists in free state. It is always found in the combined state.
Group 1- Alkali metals Group 2- Alkali earth metals Group 3-12_Transition metals Group 17-Halogens Group 18-Noble gases
What numerous property of metals do you mean? REphrase the question, please, you'll never get a serious answer on this one.
The alkali metals
Group 1 and group 2 metals
For example platinum group of metals: Pt, Ir, Os, Pd, Rh, Ru.
Never, these metals are very reactive.
Never, these metals are very reactive.
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.
Aluminium is a reactive metal and in nature only the most unreactive metals (such as gold) are found in thir pure form.
The alkali metals easily yield the one electron found in their valence shell, to bond with other elements. Since it takes so little energy to remove this electron from an alkali metal (i.e., they have a low ionization energy) these metals are never found in nature in their elemental forms (they are too reactive; i.e., their atoms so easily bond to other atoms).
Because they are highly reactive with many other elements.
Alkali is a base that dissolves in water. It is highly reactive, but never found in elemental forms of nature.
group 1 and 2
because they are too reactive to exist on their own, they bond with other elements in nature to satisfy their need for electrons
