What is the difference between Isomorphic mineral and polymorphism?
Isomorphic minerals have the same chemical composition but different crystal structures, while polymorphism refers to minerals that have the same chemical composition and crystal structure but different crystalline habits. Essentially, isomorphic minerals differ in their arrangement of atoms within the crystal lattice, while polymorphic minerals have the same atomic arrangement but different shapes or forms.
How is volcanic glass different from a mineral?
Volcanic glass does not technically contain mineral crystals. The definition of a mineral requires a crystalline structure. Secondly, the chemical composition of volcanic glass could vary widely. Minerals have definite parameters for chemical composition.
What is true of all minerals?
They are solid, naturally occurring, have a crystalline structure and a specific range of chemical formulae, and are inorganic.
Four criteria that make a mineral?
A mineral must be a solid, have a definite chemical formula, have a crystalline structure, and be naturally occuring.
How does a chemical change affect the composition of matter?
chemical change = chemical reaction. ( the composition of matter always changes). In a chemical change the matter in one thing changes, for example you will know a chemical change has occurred when the color or odor has changes or when a new gas is given off.
Do Graphite and diamonds have the same chemical compositions and different crystalline structures?
Graphite and diamonds have the same chemical composition, which is pure carbon, but their crystalline structures are different. Graphite has a layered structure, while diamonds have a tightly packed, three-dimensional crystal lattice structure. This difference in structure gives them their unique physical properties.
What If two minerals have the same chemical composition but cleave into different shapes what is true?
They have different structures.
What are solids with the same chemical composition but different structures are called?
These compounds are called isomers.
Are the chemical structures for silica and silicon dioxide identical?
The chemical composition is identical but the physical structure of the crystalline forms can vary in many ways depending on the condition of the environment where they were formed (temp, pressure, etc.)
Does non crystalline material possess the concept of allotropy or polymorphism?
No, non-crystalline materials do not exhibit allotropy or polymorphism since these concepts refer to the ability of crystalline materials to exist in different structures or forms while maintaining the same chemical composition. Non-crystalline materials lack the ordered structure needed for allotropy or polymorphism.
What is the difference between Isomorphic mineral and polymorphism?

Which material has definite properties and definite chemical composition?
Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.
Compounds with the same chemical composition may have different densities because they?
have different molecular arrangements or crystal structures that affect how closely the atoms are packed together. This can result in variations in the density of the compounds, even though they have the same chemical composition.
What can identify salt?
The chemical composition, the crystalline structure, the taste, the melting and boiling point etc.
What of the 5 characteristics of minerals?
Solid, specific chemical composition, crystalline structure, formed by nature, and inorganic.
What is chemical composition of quartz for electrode?
SiO2 is quartz- a nautural piezo-electric compound when in crystalline form.
