why are alkali metals most reactive?
52941
Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and have an oxidation state of +1. ... All these characteristics can be attributed to these elements' large atomic radii and weak metallic bonding.

Alkali metals are very good reducing agents because of their great tendency to lose electrons. The reducing character increases from Na to Cs. However, Li is stronger reducing agent than Na due to greater hydration energy.

Group 1 - the alkali metals The group 1 elements are all soft, reactive metals with low melting points. They react with water to produce an alkaline metal hydroxide solution and hydrogen. Reactivity increases down the group.

Yes Alkali Metals Are very Reactive in nature,they do not occur freely in nature. They are Very Reactive because they only have one electron in its' outermost shell. They tend to donate electrons to complete their octate.

The most reactive metals belong to the alkali metals element group. ... So, just by looking at the periodic table, you can predict lithium will be less reactive than sodium, and francium will be more reactive than cesium and all of the other elements listed above it in the element group.

Alkali metals act as strong reducing agents. Explain. ... Thus they lose a electron and get oxidize themselves ,hence reducing other compounds. This makes them strong reducing agent.

The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). ... The alkali metals are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1.

Cesium is an alkali metal, along with lithium, sodium, potassium, rubidium and francium. Alkali metals are highly reactive, have one electron in their outer shell, and do not occur freely in nature, according to ChemicalElements. ... Cesium is incredibly accurate at timekeeping and is used in atomic clocks.

The number of electrons in the outermost shell of an atom determines its reactivity. ... Halogens are highly reactive because they readily gain an electron to fill their outermost shell. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.

As you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again the elements get more reactive.

Group 1 – the alkali metals. ... All the Group 1 elements are very reactive . They must be stored under oil to keep air and water away from them. Group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.

Group 1: Alkali Metals Group 1 elements are called alkali metals because of their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water. This is because enough heat is given off during the exothermic reaction to ignite the H2(g).

Alkali metals and halogens react in different ways, and there is no standard for comparison. Halogens will react with most metals much more vigorously than alkali metals will, but alkali metals will react more vigorusly with non-metals than halogens will.

As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and electricity. The alkali metals are softer than most other metals. Cesium and francium are the most reactive elements in this group. Alkali metals can explode if they are exposed to water.

Alkali metals share many similar properties including: They are shiny, soft, metals. They are very reactive. They all have one valence electron in the outermost shell which they seek to lose in order to have a full outer shell.

Halogens are highly reactive because they readily gain an electron to fill their outermost shell. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.

The outermost electrons of the alkaline earth metals (group 2) are more difficult to remove than the outer electron of the alkali metals, leading to the group 2 metals being less reactive than those in group 1. These elements easily form compounds in which the metals exhibit an oxidation state of 2+.
