Are alkali metals considered to be very reactive or very unreactive?
Alkali metals are very reactive metals.
Why are alkali metals more reactive than other metals?
Alkali metals are more reactive as they are in group 1 and therefore has only one valence electron. With only one valence electron, its easy for them to achieve inert configuration/ noble gas configuration, which makes them so reactive.
Is alkali metals highly reactive because of its one valence electrons?
Yes, alkali metals are highly reactive because they have one valence electron that they readily donate to achieve a stable electron configuration. This makes them extremely reactive with water and air, which results in explosive reactions.
Why alkali metals is photosensitive?
Alkali metals are photosensitive because they have low ionization energies. When they absorb light, they can easily lose an electron and undergo a photoelectric effect, leading to photoemission. This property makes them reactive in the presence of light.
What makes up alkali metals special?
Alkali metals are very reactive, not dense or hard metals, monovalent, with low electronegativities, with low melting and boiling points, react violently with water, form strong bases, etc.

Why is alkali the most reactive metals?
Alkali metals are the most reactive group of metals because they have one valence electron that they readily donate to achieve a stable electron configuration. This makes them highly reactive with other elements, especially water and oxygen. They react vigorously, often producing heat and releasing hydrogen gas.

Alkali metals are very reactive, not dense or hard metals, monovalent, with low electronegativities, with low melting and boiling points, react violently with water, form strong bases, etc.
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.
How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.
What is a characteristic property of an Alkaline earth metal?
One characteristic property of alkaline earth metals is their tendency to form ionic compounds with a +2 oxidation state. This makes them readily react with nonmetals to form stable compounds. Additionally, alkaline earth metals have relatively low electron affinities, making them less reactive than alkali metals.
Is noble gases metals that are more reactive than the transition elements but less reactive than the alkali metals?
No, noble gases are not metals; they are a group of non-metal elements. Noble gases are the least reactive elements because they have a full valence shell of electrons, which makes them stable and unlikely to form chemical bonds with other elements. Alkali metals are the most reactive metals, while transition elements have varying reactivity levels depending on the element.
What do the alkali group 1 metals have in common?
Alkali group 1 metals have one valence electron, which makes them highly reactive. They have low melting and boiling points and are soft metals that can be easily cut with a knife. These metals also tend to form ionic compounds due to their tendency to lose their single valence electron.
How many electrons do alkali metals have on there auter shell how does this affect the properties of a metal?
Alkali metals have 1 electron in their outer shell, which makes them highly reactive. They easily lose this electron to form positively charged ions, making them good reducing agents. This electron configuration and reactivity are key factors influencing the properties of alkali metals.
