because aklai are soluble in water with compltely and alkai earth metal are partially dissolve in water thats they are called true hydrides
The generic formula for an alkaline earth hydroxide is M(OH)2
No. The alkali and alkaline earth metals are very reactive.
MH2, M= alkaline earth metal.
It is not a alkaline metal.It is a alkaline earth metal.
No. Scandium is in column 3 of a periodic table, and the alkaline earth metals are in column 2.
alkai metals, alkaline earth metals, lanthanoids, actinoids, transistion metals, poor metals, other non-metals, noble gases.
Group 2 elements in the periodic table are the alkaline earth metals.
The elements of the second group are called the Alkaline Earth metals.
Group 2 elements are called alkaline earth metals because they form alkaline solutions when they react with water. The term "earth" indicates that these elements were found in the earth's crust, while "alkaline" describes the basic nature of the compounds they form.
Alkaline earth metals
There are three types of hydride: saline, metallic and covalent (there are alternative names for the types of hydride, but these are most common). Saline hydrides have crystalline, salt like structures, and are formed with hydrogen and the group 1 and group 2 metals (the alkali metals and the alkaline earth metals). Metallic hydrides are brittle solids with fairly simple structures, generally formed between hydrogen and the transition metals. They can often have non-integer stoichiometries, e.g. ZrH1.3. Covalent hydrides are formed between hydrogen and the p-block elements, and tend to be gases as room temperature (there are exceptions to this, because of hydrogen bonding).
Covalent hydrides are all the other compounds of hydrogen wher hydrogen is covalently bonded- typiccally sharing an electron pair as in CH4 (methane) which could be called carbon tetrahydride although this is not a recognised name.The term hydride is usually applied to ionic compounds of hydrogen and metals of group 1A (alkali metals) and group 2A (alkaline earth metals) (notale exception Be) . In these hydrides,metal atoms form positive ion by losing valence electronsand hydrogen forms negative ion gaining that electron in order to complete its shell.
The elements present in it are called alkaline earth metals. It contains beryllium, magnesium ....
Alkali earth metals are named after their oxides, alkaline earth.
These are called alkali earth metals. Look it up for explanation as to why.
Group 2 is called Alkaline Earth metals
They are usually called alkaline earth metals.
