Other common compounds of calcium include: calcium sulfate (CaSO 4 ), also known as gypsum, which is used to make dry wall and plaster of Paris, calcium nitrate (Ca(NO 3 ) 2 ), a naturally occurring fertilizer and calcium phosphate (Ca 3 (PO 4 ) 2 ), the main material found in
The Importance of d-block Transition Metals
The Importance of d-block Transition Metals By: Daniel Bates The d-block transition metals have great importance in our lives. They are building blocks for life and are found directly in the center of the periodic table. The d-block simply means that the elements’ d-orbitals are the last to get occupied according to the building-up principle.
Alkaline-earth Metals | Encyclopedia
ALKALINE EARTH METALSCONCEPT The six alkaline earth metals — beryllium, magnesium, calcium, strontium, barium, and radium — comprise Group 2 on the periodic table of elements. This puts them beside the alkali metals in Group 1, and as their names suggest, the two families share a nuer of characteristics, most notably their high reactivity. . Also, like the alkali metals, or indeed any
