∙ 13y agothe alkali metals (Li,Na,K,Rb,Cs,Fr) are highly reactive and are usually stored in mineral oil or kerosene.The alkali metals show a number of trends when moving down the group - for instance: decreasing electronegativity, increasing reactivity, and decreasing melting and boiling point. Their densities generally increase, with the notable exception that potassium is less dense than sodium, and the possible exception of francium being less dense than caesium. (The highly radioactive element francium only exists in microscopic quantities.)

Which properties of alkali metals unusual metals?
Alkali metal forms Alkali while metals form bases.
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.
What properties do the alkali metals share?
Malleable, ductile, good conductors.
One of the properties of alkali metals is that they dont react with water?
False!
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
Are alkali metals conductive?
yes, all metals conduct. It is one of their defining properties.
What are the common properties of halogen?
highly reactive with alkali metals and alkaline earth metals
What is Properties of alkali metals?
Low melting and boiling point
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.

False!
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.
What is reactivity of properties of metals?
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.
