What is dolomites crystal structure?
The crystal structure of dolomite is trigonal, meaning that it has threefold symmetry. It consists of layers of carbonate ions alternating with layers of magnesium and calcium ions. This results in a rhombohedral crystal shape.
How are the shapes of molecules of polyatomic ions related to the number of electron pairs surrounding the central atom?
VSEPR theory predicts that the electron pairs in bonds and lone pairs repel one another and this gives rise to the shape. Lone pairs repel bonding pairs more than bonding pairs repel one another. It is often taught that electrostatic repulsion is the major cause of this but the man who invented the theory, Prof. Gillespie, says that the repulsion is due to the Pauli Exclusion Principle. See wikipedia link for a reasonable description.
What is a crystal and what determines a crystals shape?
A crystal is a mineral where all of the atoms are in a row, this is what makes it kind of clear. What determines its shape is the amount of space it has to form in and will usually have triangular pyramidal edges.

What molecules or ions has a linear pair pcl5 becl2 clo4- ph3?
Among the molecules and ions listed, BeCl₂ (beryllium chloride) has a linear geometry due to its sp hybridization and the presence of two bonding pairs and no lone pairs of electrons. In contrast, PCl₅ (phosphorus pentachloride) has a trigonal bipyramidal shape, ClO₄⁻ (perchlorate) is tetrahedral, and PH₃ (phosphine) has a trigonal pyramidal shape. Thus, only BeCl₂ exhibits a linear molecular geometry.

Is AlCl3 a trigonal planar?
It depends on the phase and the temperature Solid AlCl3 has each aluminium is 6 coordinate, surrounded by 6 chlorine atoms in an octahedral formation. The best description here is a ionic bonding. Interestingly just below melt temperature the conductivity rises indicating free ions. AlCl3 in the melt is found as dimer Al2Cl6 with four coordinate aluminium. Two chlorines bridging the aluminium atoms. In this aluminium achieves its octet and the bond angles are in line with VSEPR theory. At high temperature the dimers dissociate to monomeric AlCl3 which is trigonal planar, following VSEPR theory.
What differentiates molecules from ions?
Molecules are electrically neutral. Ions have electric charges.
How do ions become molecules?
Ions and molecules are the results of two different types of bonds. Ions are the result of ionic bonds and molecules are the result of covalent bonds.
What two molecules are formed by the Hydrogen ions?
Hydrogen ions can form water molecules (H2O) by combining with hydroxide ions (OH-) or hydronium ions (H3O+).
Why B cl3 is trigonal planar while Alcl3 is polymeric in nature?
Boron trichloride (BCl₃) is trigonal planar due to its three equivalent bonding pairs of electrons around the boron atom, which leads to a symmetrical arrangement with 120-degree bond angles. In contrast, aluminum chloride (AlCl₃) is polymeric in nature, especially in solid form, because it tends to form a network of Al-Cl bonds through dimerization and further polymerization, resulting in a three-dimensional structure. This occurs due to the presence of vacant d-orbitals in aluminum, allowing for coordination with multiple chloride ions, unlike the electron-deficient boron in BCl₃.
What is a substance containing molecules and ions?
Water: H2O molecules, H+ and OH- ions
