false, alkali metals. There are only six metals in this category including beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). The alkaline earth metals are in the second group of the periodic table. chemical properties of alkaline earth metals The chemical reactions of the alkaline earth metals are quite comparable to that of alkali metals. The six alkaline earth metals — beryllium, magnesium, calcium, strontium, barium, and radium — comprise Group 2 on the periodic table of elements. Property of the alkaline earth metals that increases with their atomic number: View solution E ∘ for M 2 + ( a q ) + 2 e − → M ( s ) (where M = Ca, Sr or Ba) is nearly constant.

Properties of alkaline Earth metals include a) gray or silver color. 2. is not studied at GCSE. Learn more about the Alkaline Earth Metals for IIT JEE ( Main and Advanced) at Vedantu.com. As with the alkali metals, the properties depend on the ease with which electrons are lost. The energy it takes to remove an electron from an element is called the ionization energy. Alkaline earth metals are on the periodic table of elements in group IIA, the second column from the left. The alkaline earths have two electrons in the outer shell. They readily lose their two outermost electrons to form cations with charge +2. The alkaline earth elements are the metallic elements found in the second group of s-block after the group (1 A). (iii) These metals lose two electrons to acquire the nearest noble gas configuration. For shortcuts to this
The formulas of typical alkaline-earth compounds, such as calcium chloride (CaCl 2) and calcium oxide (CaO), may be contrasted with the corresponding compounds of the alkali metals (which contain M + ions), sodium chloride (NaCl) and sodium monoxide (Na 2 O). Alkaline earth metals are reactive but less than alkali metals. they have the same number of

Some characteristics of alkaline earth metals are: An oxidation number of +2 which makes them very reactive. earth metals are harder than the alkali
Comparing with the alkali metals is denser than alkaline earth metals in the same period. ALKALI AND ALKALINE EARTH METALS are a group of chemical elements in the periodic table with very similar properties. They are located on the left side of the modern periodic table. Alkali metals have one electron in their outer shell, which is loosely bound. Properties of the Alkaline Earth Metals. losing their 2
But due to smaller size and greater charge and hence high ionisation energy, these are much less reactive than the corresponding alkali metals. Strontium, barium and radium are
