What else can I help you with?
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.
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 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.
What are physical properties for alkali metals?
Alkali metals are powerful reducing agents, they give up one electron easily. They are extremely reactive.
What are characteristic properties of alkaline earth metals?
they are harder than alkali 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?

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.
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.
The three main groups of elements are?
The three main groups of elements are metals, nonmetals, and metalloids. Metals are typically solid, shiny, malleable, and good conductors of electricity. Nonmetals are generally dull, brittle, and poor conductors of electricity. Metalloids have properties that are intermediate between metals and nonmetals.
What are three radioactive are?
They are Alkali metals, Alkaline Earth metals, and Carbon 16. ----
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.
Is lithium hard?
No, in comparison to the rest of the metals, lithium (as an alkali metal) would be called a soft metal. All the alkali metals could be cut with a knife, but still retain properties of metals.
