What Chemical Elements Are Found in Limestone? | eHow

The first element found in limestone is calcium; the symbol for calcium is Ca. Calcium has atomic number 20, meaning it has 20 protons in its nucleus. The pure element has 20 electrons. Like other metals in the same group, the alkaline earth metals, calcium is easily ionized, so in nature it's found as part of other compounds (like calcium ...

This paper presents a comparative study of Physical-Chemical characteristics of Limestone and Basalt (from Senegalese quarries). First, chemical tests show that Basalt is richer in silica 51.59% versus 2.84% for Limestone. Basalt is made up of silica minerals and essentially carbonated minerals with a CaO percentage of 50.05%. Chemical results also show that Basalt is richer in …
