Celestine or celestite is a mineral consisting of strontium sulfate. The mineral is named for its occasional delicate blue color.Strontianite is a mineral consisting of strontium carbonate, named after the village of Strontian, Lochaber, Scotland, where it was first discovered. This mineral is white, greenish, or yellowish in color, usually occurring in fibrous massive forms, but sometimes in prismatic crystals.

Well, I find your question a bit fuzzy but I think this is what your looking for:Covalent bonding is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, or between atoms and other covalent bonds. In short, attraction-to-repulsion stability that forms between atoms when they share electrons is known as covalent bonding.A coordinate covalent bond (also known as dative bond) is a description of covalent bonding between two atoms in which both electrons shared in the bond come from the same atom. The distinction from ordinary covalent bonding is artificial, but the terminology is popular in textbooks, especially those describing coordination compounds. Once the bonds have been formed using this, its strength and description is no different from that of other polar covalent bonds.

when a metal (usually an cation) reacts with a non-metal (usually a anion) to form/bond into a ionic compound. that's all i knowAnd there is one more factor...

In terms of chemistry, ionic compounds are a chemical compound in which ions (atoms with a positive or negative charge) are held together in a lattice structure by bonds forged by the ions (ionic bonding.). The positively charged ion is usually a metallic element/molecule and the negatively charged ion is a non-metallic element and/or molecule.

A solvent is a substance that dissolves another substance, called a solute, to form a homogenous mixture called a solution. A solvent may be solid, liquid or gas, while a solute may also be the other phases.
