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.

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.

What are the reactions with alkali metals and water like?

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.


Why the melting point boiling point and densities of alkaline earth metals are higher than alkali earth metals?

Alkaline earth metals do not exist , only alkali earth metals


Are alkali and alkaline earth metals are not reactive?

No. The alkali and alkaline earth metals are very reactive.


What created when alkaline earth metals and water combined?

When they are reacted, a base and hydrogen gas is produced. This reaction is exothermic.


Which of these groups of metals is the most active alkaline earth alkali halogen coinage?

The alkali group of metals is the most active.

Hydrogen can by generated, for example, from the reaction between alkali metals and water.


Does hydrogen behave like an alkali metal?

Yes, chemical similarities exist between hydrogen and alkali metals; also the electron configuration has a parallel.


Why hydrogen is placed above alkali metals and not above non metals in modern periodic table?

The electron configuration of hydrogen is similar with that of alkali metals.


Which group has 1 valence electron?

Group 1- the Alkali metals and also Hydrogen.


In what way is hydrogen like the alkali metals?

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.


Why hydrogen is placed in alkali metals or in first group of modern periodic table?

As with all alkali metals, hydrogen has one electron in its outermost shell.


What gas is chemically similar to alkali metals?

(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.)


Can Hydrogen make bond with alkali metals?

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.


Which element of the alkali metals is really not a metal?

hydrogen


How is hydrogen done?

For example hydrogen is released when alkali metals react with water.


What is the family of hydrogen?

Hydrogen is placed in group 1, along with alkali metals
