Chemically they are completey different in reactivity. The similarities are they are both gaseous in the elemental state and both only need to gain 1 electron to get to a stable inert gas configuration. They can also forms salts with metals such as sodium chloride and sodium hydride.
...i dont think there is any likings to them ask a scientist.
there is no similarities between these two groups.
However, if alkali metals lose one electron, they achieve the configuration of the nearest noble gas.
They have 1 electron in outer shell. They tend to make cations.
Both are diatomic. Both are molecular substances and have low boiling points. Both can form negative ions. Both form binary compounds with chlorine and iodine.
1) Alkali metals are stored in oil to minimise reaction with oxygen or water, it's a physical barrier towards air but the alkali metals still gradually corrode a traces of oxygen and water diffuse through. The reaction of alkali metals with water gets more violent for elements lower in the group e.g. (Li < Na < K < Rb < Cs). Adding them to water will cause an explosion due to the extremely exothermic nature of reaction, and can be rather dangerous and some alkali metals can react violently with just moisture in the air. Most of the alkali metals float on the top of the water, depending on how big the alkali metal is determines the size of the reaction this is because they're less dense that water itself and also during the reaction the alkali metals give of hydrogen gas which is quite flammable. Alkali Metal + Water » Metallic Hydroxide + Hydrogen The francium would be like any other alkali metal, it would be very violent like the other alkali metals.
Alkaline earth metals do not exist , only alkali earth metals
No. The alkali and alkaline earth metals are very reactive.
When they are reacted, a base and hydrogen gas is produced. This reaction is exothermic.
The alkali group of metals is the most active.
Alkali Metals
Hydrogen can by generated, for example, from the reaction between alkali metals and water.
Yes, chemical similarities exist between hydrogen and alkali metals; also the electron configuration has a parallel.
The electron configuration of hydrogen is similar with that of alkali metals.
Group 1- the Alkali metals and also Hydrogen.
Hydrogen has a single valence electron, just like the alkali metals. Unlike them, however, hydrogen prefers to covalently bond instead of forming an ionic bond.
As with all alkali metals, hydrogen has one electron in its outermost shell.
(A similar relationship exists in Group 1, which includes hydrogen and the alkali metals. All have the same valence configuration, but hydrogen is never included as a member of the alkali metals family.)
No, hydrogen is a nonmetal. It is grouped with the alkali metals because it has a similar outer shell electron configuration as they do. Hydrogen is something of an oddball among elements. It is rather unique, but share some characteristics with both the halogens and the alkali metals. When the periodic table is divided into groups (noble gasses, halogens, alkali metals, etc.) hydrogen is usually put in its own group.
hydrogen
For example hydrogen is released when alkali metals react with water.
Hydrogen is placed in group 1, along with alkali metals
