Why did Dmitri mendeleev think gold and silver were alkali metals?
Dmitri Mendeleev did not think gold and silver were alkali metals. He classified gold and silver as transition metals in his periodic table based on their chemical and physical properties. Alkali metals are a different group of elements.
Are alkali metals electro-positive?
Yes they are!even though they are very soft, reactive and not as widely used as much as transition metals eg. in construction they still have other metallic properties, such as metallic bonding.Yes all alkali metals are metals.
Are elements potassium and sodium metals or nonmetals?
Potassium and sodium are both metals. They belong to the alkali metal group of the periodic table, which is known for its highly reactive properties.
Are metalloids found within the alkali metals?
No, metalloids are not found within the alkali metals. Alkali metals are located in Group 1 of the periodic table and are characterized by their high reactivity and metallic properties. Metalloids, which have properties intermediate between metals and nonmetals, are typically found along the staircase line that separates metals from nonmetals in the periodic table, primarily in Groups 13 to 16.
Is alkali metals a group 1 elements?
No that is group 2. Group 1 is called Alkali metals.

What are characteristic properties of alkaline earth metals?
they are harder than alkali metals
Are alkalai metals metal?
According to the scientific definition of a metal yes, Alkali metals are considered metals, but it is important to understand that alkali metals have different properties from regular metals. The alkali metals exhibit many of the physical properties common to metals, although their densities are lower than those of other metals. Alkali metals have one electron in their outer shell, which is loosely bound. This gives them the largest atomic radii of the elements in their respective periods. Their low ionization energies result in their metallic properties and high reactivities. An alkali metal can easily lose its valence electron to form the univalent cation. Alkali metals have low electronegativities. They react readily with nonmetals, particularly halogens.
What are the physical features of alkali metals?
They are light, soft, silvery metals.
What are the common properties of halogen?
highly reactive with alkali metals and alkaline earth metals
Are alkali metals conductive?
yes, all metals conduct. It is one of their defining properties.
What is Properties of alkali metals?
Low melting and boiling point
Are alkali metals electro-positive?
Yes they are!even though they are very soft, reactive and not as widely used as much as transition metals eg. in construction they still have other metallic properties, such as metallic bonding.Yes all alkali metals are metals.
Are elements potassium and sodium metals or nonmetals?
Potassium and sodium are both metals. They belong to the alkali metal group of the periodic table, which is known for its highly reactive properties.
Is alkali metals can be cut simply by knife but iron cannot because of alkali metals have?
Alkali metals can be cut with a knife because they are soft and have low melting points. Iron cannot be cut easily with a knife because it is a strong and hard metal. The differences in properties between alkali metals and iron make alkali metals easier to cut with a knife.
What are the similarities of potassium and francium?
Lithium, sodium potassium, caesium, rubidium and francium are all alkali metals; consequently they share many chemical and physical properties.
How are alkaline earth metals different from alkali metals in terms of their properties and reactivity?
Alkaline earth metals have higher melting points and densities compared to alkali metals. They are less reactive and have two valence electrons, while alkali metals have one valence electron and are more reactive.
