No. There are six (maybe seven, depending on what source) crystal systems that a mineral crystal may be classified into.
See link below for information.
No. Crystals have an organized internal structure.
No no no! no two mierels have the exactsame crystalline structure, and idk the exacts but no it is not the exact same. so... any more questions?
No, not all crystals have the same shape.
It's not that only alum makes big crystals.. There are so many compounds that can make big crystals. Even Sodium Hydroxide makes very good and big crystals. For crystals you need a uniform arrangement of atoms in space. For big crystals all you need is patience. The slower is the crystallization process the bigger crystals are formed. What industries do is called seeding. They make a good concentrated solution of the compound whose crystals are needed and then they put a crystal of the same compound in the solution. The new crystals form and attach to the crystal making quick and big crystals.
we know that the formula of ethyl alcohol (C2H5OH) and dimethyl ether(CH3OCH3). when u notice the molecular formula of both the compounds is C2H6O. but they are different in their properties. to be simple ISOMERS OF COMPOUNDS WHICH HAVE SAME MOLECULAR FORMULA BUT DIFFER IN STRUCTURE, FUNCTIONAL GROUP, POSITION OR SPATIAL ARRANGEMENT.
The chemical properties of atoms are significantly changed when they form compounds. When elements combine to form compounds it is called a chemical reaction. The compound is then a collection of molecules and each molecule has are still the same atoms as one started with, but the arrangement of the electrons in the atoms has changed.
All hydrogen atoms are the same but they are different from the atoms of other elements.
No, they differ in biological activity because a specific arrangement of atoms in a specific enantiomer may react with a particular enantiomer of another compound present in biological systems while other does not.
No. Not all crystals have the same structure in them. Crystals may have different atoms formed in them and so it proves they are not the same.
A material made entirely out of the same atoms. ie. the atoms all have the same electron arrangement.
ALLOTROPE
The arrangement of atoms is the same in synthetic and natural diamond.

labor
They all keep time: Cesium atoms, quartz crystals, and pendulums all vibrate at a constant frequency (not the same frequency for each substance.) With current technology, cesium atoms are the most precisely constant.
Stereoisomerism is a type of isomerism were the atoms that are in the molecules are the same and there arrangement are the same but there spatial arrangements are different to eachother.
If the atoms of the same element (not only carbon!) occur in different arrangements, they are said to be different allotropes.

Two identical electron configuration doen't exist for atoms.
