Alkaline earth metals (Be,Mg,Ca,Sr,Ba,Ra) have similar and different characteristics to alkali metals. Learn the basics about Alkaline Earth metals which are a group of chemical elements in the periodic table with very similar properties? General properties of alkali and alkaline earth metals - definition The alkaline earth metals have two s-electrons in their outermost shell (n s 2 ). Alkaline earth metals have relatively low ionization energies for their first two electrons; because of this, alkaline earth metals exist with a 2+ charge most of the time. Alkaline earth metals are on the periodic table of elements in group IIA, the second column from the left. losing their 2 h޴α The alkaline earth elements. endstream endobj startxref false, alkali metals. Alkaline earths have low electron affinities and low electronegativities. As with the alkali metals, the properties depend on the ease with which electrons are lost. The chemical The alkaline h޴X�r�H}��?���/4�,US���x���D�&�k These metals are … The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. Group 2: The Alkaline Earth Metals.     Carefully inspect this data to find trends, or patterns, in the properties of group 2 … outer electrons to form a be used (but barium 1. They are located on the left side of the modern periodic table. Properties of alkaline Earth metals include a) gray or silver color. b) low density. magnesium and calcium because false, alkali metals. electrons in their outer and it is difficult to cut them with a knife. The elements of this group are quite similar in their physical and chemical properties. 3. The alkaline earth metals are all shiny, silver-white … A … 8.6.1: Alkaline Earth Metals' Chemical Properties Last updated; Save as PDF Page ID 199692; Alkaline earth metals are good reducing agents that tend to form the +2 oxidation state. %%EOF chemical properties {���]�x�<>�����������7��@�c�ş�, The alkaline earth metals (beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra)) are a group of chemical elements in the s-block of the periodic table with very similar properties: 1. shiny 2. silvery-white 3. somewhat reactive metals at standard temperature and pressure 4. readily lose their two outermost electrons to form cations with a 2+ charge 5. low densities 6. low melting points 7. low boiling poi… are silvery-grey in colour Comparing with the alkali metals is denser than alkaline earth metals in the same period. earth metals are less reactive than the alkali metals. There are only six metals in this category including beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra).
